I searched for a shortcut command that would comment/uncomment a block for repl.it. I'm working on a python 3 project and I often need to comment a big section of my code. Is there a shortcut command for that?

Same for me. I followed the previous answer but could not find autocomplete-plus (June 2018). I installed autocomplete and now both packages work just fine.

I have just installed the Atom IDE and the package autocomplete-python (on Windows). But the package is not working. Do I have to make any setting changes? (I have disabled autocomplete-plus and autocomplete-snippets). Do I need to separately install Jedi?

Late to the party, but I had the same issue and resolved it by adding a path to my site-packages for one of my virtual environments in the settings. On the toolbar, go to File-> Settings -> packages. Find your autocomplete-python package. Go to the settings of the autocomplete-python package. Scroll down to "Extra Paths For Packages". Copy and paste a path location to your site packages. e.g: C:\Users\my_username\Miniconda3\envs\my_env_name\Lib\site-packages Celebrate :)

I also had the same problem while trying to use the django-atom autocomplete snippet and after reading different articles on it here is how I go about it. Go to the directory of the installed autocomplete package, in this case here: C:\Users\user.atom\packages\django-atom Go to the snippet folder and you'll find a .cson file, right click and open it with an editor in this case here is the directory: C:\Users\user.atom\packages\django-atom\snippets Copy everything inside the file and go back to the snippets.cson file in .atom parent directory, in this case here: C:\Users\user.atom Right click and open the snippets file with an editor, scroll down and paste everything you copied earlier into the file then save. Bro, now you can enjoy your beautiful snippets.

If autocomplete-python in Atom not working with Python 3.7 In windows, go to: C:\Users\username\.atom\packages\autocomplete-python\lib\jedi\parser Or in linux: cd ~/.atom/packages/autocomplete-python/lib/jedi/parser Duplicate file named "grammar3.6.txt" and change it to "grammar3.7.txt" It's worked for me with python 3.7!

It worked when I enabled autocomplete-plus. It seems autocomplete-plus is required for autocomplete-python to work. (I had initially followed a youtube video in which autocomplete-plus and -snippets were disabled and then autocomplete-python was installed.)

Let me talk for a case with Android emulator- gemu-system_86_64. Have experienced the same error that “Process finished with exit code -1073740791 (0xC0000409)” Have played with bios settings, path to java, memory and disk speed enhansments, rolling back old original card drivers, Nvidia supports - no result. Then I returned all default settings to above ones and: Right clicked on Desktop and selected 'Nvidia control panel' -> 3d settings -> Manage 3d settings. You can see there two tab: global settings. Put all of them as clamp, off or '1'. And in 'programm settings' tab navigated to emulator app and also disabled all what s possible. Now all work just fine. If any in future you can change them for a specific application. Perhaps this will help somebody.

These requirements are more or less straightforward to follow. Given that you will have a persistent database that can share the state of each file with multiple sessions - and even multiple deploys - of your system - and that is more or less a given with Python + PostgreSQL. I'd suggest you to create a Python class with a few fields yuu can use for the whole process, and use an ORM like SQLAlchemy or Django's to bind those to a database. The fields you will need are more or less: filename, filpath, timestamp, check_status - and some extra like "locked_for_checking", and "checker" (which might be a foreignkey to a Users collection). On presenting a file as a sugestion for a given user, you set the "locked_for_checking" flag - and for the overall listing, yu create a list that excçuds files "checked" or "locked_for_checking". (and sort the files by timestamp/size or other metadata that attends your requirements). You will need some logic to "unlock for checking" if the first user does not complete the checking in a given time frame, but that is it.

Firstly, this question isn't a request for code suggestions- it's more of a question about a general approach others would take for a given problem. I've been given the task of writing a web application in python to allow users to check the content of media files held on a shared server. There will also likely be a postgres database from which records for each file will be gathered. I want the web app to: 1) Suggest the next file to check (from files that have yet to be checked) and have a link to the next unchecked file once the result of the previous check have been submitted. 2) Prevent the app from suggesting the same file to multiple users simultaneously. If it was just one user checking the files it would be easier, but I'm having trouble conceptualising how i'm going to achieve the two points above with multiple simultaneous users. As I say, this isn't a code request i'm just just interested in what approach/tools others feel would be best suited to this type of project. If there are any python libraries that could be useful i'd be interested to hear any recommendations. Thanks

I would suggest going with the data pipeline into S3 approach. And then have a script to read from S3 and process your records. You can schedule this to run on regular intervals to backup all your data. I don't think that any solution that does a full scan will offer you a faster way, because it is always limited by read throughput. Another possible approach is to use dynamoDB stream and lambdas to maintain second table in real time. Still you will first need to process existing 15 GB once using approach above, and then switch to lambdas for keeping them in sync

I have a table of size 15 GB in DynamoDB. Now I need to transfer some data based on timestamps ( which is in db) to another DynamoDB. What would be the most efficient option here? a) Transfer to S3,process with pandas or someway and put in the other table (data is huge. I feel this might take a huge time) b) Through DataPipeLine (read a lot but don't think we can put queries over there) c) Through EMR and Hive (this seems to be the best option but is it possible to do everything though a python script? Would I need to create an EMR Cluster and use it or create and terminate every time? How can EMR be used efficiently and cheaply as well?)

I downloaded Python 3.6 from Python's website (from the download page for Windows) and it seems only the interpreter is available. I don't see anything else (Standard Library or something) in my system. Is it included in the interpreter and hidden or something? I tried to install ibm_db 2.0.7 as an extension of Python DB API, but the installation instructions seem too old. The paths defined don't exist in my Win10. By the way, I installed the latest Platform SDK as instructed (which is the predecessor of Windows 10 SDK, so I had to to install Windows 10 SDK instead). I also installed .NET SDK V1.1, which is told to include Visual C++ 2003 (Visual C++ 2003 is not available today on its own). I considered to install VS2017, but because it was too big (12.some GB) I passed on that option. I am stuck and can't proceed for I don't know which changes happened from the point the installation instructions have been written and what else I need to do. How can I install python with the ibm_db package on Windows 10?

for python libraries you can always use pip, which is a python package installer. if you are using python 3.6 then you already have pip. just make sure you're using pip from the main command line not the python terminal

Any Python class is free to define various operations however it likes. Strings happen to implement the sequence protocol (meaning that iteration and [i] item access behave the same as lists), but also implement __contains__, which is responsible for x in y checks, to look for substrings rather than just single characters. It is common for x in y membership testing to mean "x will appear if you print all the elements of y", but there's no rule saying that that has to be the case.

My book says - Strings and lists are actually similar, if you consider a string to be a “list” of single text characters. Suppose that I have a string namely name=Zophie. Now this string should have some resemblance with a list. So I type in another code that would tell me what should the items of that list be. The code goes like - for i in name: print(‘* * * ‘ + i + ‘ * * *') The output is: * * * Z * * * * * * o * * * * * * p * * * * * * h * * * * * * i * * * * * * e * * * This clearly shows that the list items of name are Z,o,p,h,i,e. Now if I try to check wether the list has an item ’Zop' by using: Zop in name It returns True! That is, Python says that Zophie contains an item namely ’Zop’ but when I tried to list all the items using the for command, Zop didn’t show up. What’s happening here?

Why do any of the ordered characters in a string appear to be a part of a list which is equivalent to that string?

No, Torch7 use static computational graphs, as in Tensorflow. It is one of the major differences between PyTorch and Torch7.

Pytorch have Dynamic Neural Networks (defined-by-run) as opposed to Tensorflow which have to compile the computation graph before run. I see that both Torch7 and PyTorch depend on TH, THC, THNN, THCUNN (C library). Does Torch7 have Dynamic Neural Networks (defined-by-run) feature ?

Is Torch7 defined-by-run like Pytorch?

Open the text editor like nano , vim or gedit and open the .bashrc file , nano ~/.bashrc and create the bash alias, To do so add the following line into the .bashrc file: alias python='/usr/bin/python3.6' Save the file and re-open the terminal. Edit: Similarly, if you don't want to create the direct alias. As @exprator suggested above you can also use python command for python 2 and python3 to use Python 3 version

Great question. This is within scope of this forum. The answer is "it depends". Cytoscape apps themselves must be Java (or something that runs in JVM, though there's only documentation support for Java and the forums will give best advice for Java). However, the Cytoscape Cyberinfrastructure (CI) allows Python-based services (e.g., the Diffusion service) called by Cytoscape apps (e.g., the Diffusion app). The service must be deployed somewhere on the web (e.g., in a Kubernetes cluster). If you'd like help with that route, you'll find enthusiastic support ... please e-mail the cytoscape-app-dev at googlegroups.com forum directly.

Since X is a numpy array, you can do X.shape instead of the repeated len. I expect it to show (13934, 74). I expect Y.shape to be (13934,). It's a 1d array, which is why Y[0] is a number, numpy.int64. And since it is 1d, transpose (swapping axes) doesn't do anything. (this isn't MATLAB where everything has at least 2 dimensions.) It looks like you want to create an array that has shape (13934, 75). To do that you'll need to add a dimension to Y. Y[:,None] is a concise way of doing that. The shape of that is (13934,1), which will concatenate with X. If that None syntax is puzzling, try, Y.reshape(-1,1) (or reshape(13934,1)).

I have a matrix X which has len(X) equal to 13934 and len(X[i]), for all i, equal to 74, and I have an array Y which has len(Y) equal to 13934 and len(Y[i]) equal to TypeError: object of type 'numpy.int64' has no len() for all i. When I try np.vstack((X,Y)) or result = np.concatenate((X, Y.T), axis=1) I get ValueError: all the input array dimensions except for the concatenation axis must match exactly What is the problem? When I print out Y it says array([1,...], dtype=int64) and when I print out X it says array([data..]) with no dtype. Could this be the problem? I tried converting them both to float32 by doing X.view('float32') and this did not help.

I want to share data between programs that run locally which uses different languages, I don't know how to approach this. For example, if I have a program that uses C# to run and another that uses python to run, and I want to share some strings between the two, how can I do it? I thought about using sockets for this but I'm not sure that this is the right approach, I also thought about saving the data in a file, then reading the file from the other program, but, it might even be worse than using sockets. Note that I need to share strings almost a thousand times between the programs

There are a lot of ways to do so, I would recommend you reading more about IPC (Inter Process Communication) - sockets, pipes, named pipes, shared memory and etc... Each method has it's own advantages, therefore, you need to think about what you're trying to achieve and choose the method that fits you the best.

I want to share data between programs that run locally which uses different languages, I don't know how to approach this. For example, if I have a program that uses C# to run and another that uses python to run, and I want to share some strings between the two, how can I do it? I thought about using sockets for this but I'm not sure that this is the right approach, I also thought about saving the data in a file, then reading the file from the other program, but, it might even be worse than using sockets. Note that I need to share strings almost a thousand times between the programs

If you just go ahead and change the model name in your models.py file, the "makemigrations" command is usually smart enough to pick it up. It will ask you if you changed the model name and create a migration to rename the table accordingly if you confirm.

Keras pop() removes the last (aka top) layer, not the bottom one. I suggest you use model.summary() to print out the list of layers and than subsequently use pop() until only the necessary layers are left.

In Keras there is a feature called pop() that lets you remove the bottom layer of a model. Is there any way to remove the top layer of a model? I have a fully saved pre-trained Variational Autoencoder and am trying to only load the decoder (the bottom four layers). I am using Keras with a Tensorflow backend.

Apologies for the long title. What I want to do is to be able to spawn a bullet to the left or right of the centre of an object, the player, which can turn in a full 360 degrees to the left and right. At the moment I am using x = hypotenuse * cos(player angle) and y = hypotenuse * sin(player angle). This works very strangely with it working while pointing upwards, with the bullet spawning on the right as intended, but as soon as it is angled downwards it starts spawning on the left. I have some teacher and we have done some playing around, however they have not been able to help too much as of yet.

IDLE and pycharm are development tools. When you run the code as webpage, you shouldn't use them. In particular -- idle is an editor for one file at a time, while pycharm is better for project development. Any way, you can use any text editor for editing the python files.

Oh yes, Sir! Use the PAIR-PAIR or even the XREQ-XREP ought make it. The best next step is to carefully read the respective Scalable Formal Communication Pattern archetypes' access-points' API documentation, so as to cross-check, that all pieces of pre-wired behavioural logic meet your Project needs and voilá, harness them in your messaging setup and tune-up the settings so as to meet you performance and latency needs. That is this simple ( thanks to all the genuine knowhow hidden in these builtins ). Using for years this very sort of inter-platforms integration among Python + C/MQL4 and other computing nodes, so well worth one's time to learn the powers and strengths of ZeroMQ.

The best way to write this program would be something like this: Open the first excel file, you might find it easier to open if you export it as a CSV first. Create a Dictionary to store word and Cell Index Pairs Iterate over each cell/word, add the word to the dictionary as the Key, with the Cell Reference as the Value. Open the second excel file. Iterate over each cell/word, check if the word is present in the Dictionary, if it is, you can print out the corresponding cells or store them however you want.

I don't know why nobody has suggested it, but you can always pickle things and put the result into a binary field. The advantages of this method are that it will work with just about any database, it's efficient, and it's applicable to more than just arrays. The downside is that you can't have the database run queries on the pickled data (not easily, anyway).

I was wondering if it's possible to store an array in a Django model? I'm asking this because I need to store an array of int (e.g [1,2,3]) in a field and then be able to search a specific array and get a match with it or by it's possible combinations. I was thinking to store that arrays as strings in CharFields and then, when I need to search something, concatenate the values(obtained by filtering other model) with '[', ']' and ',' and then use a object filter with that generated string. The problem is that I will have to generate each possible combination and then filter them one by one until I get a match, and I believe that this might be inefficient. So, I hope you can give me other ideas that I could try. I'm not asking for code, necessarily, any ideas on how to achieve this will be good.

Storing monetary values in counts of the smallest denomination is a common practice. It ensures that you can always count full values and reduces the risk of rounding errors associated with floating point types. Whether an integer type is enough depends on the maximum value you want to store. Firebase Database internally supports signed 64-bit longs (-2^63 ... 2^63-1). Note that JavaScript uses 64-bit double values internally so some large integers (greater than 2^53) are not precisely representable and will lose precision.

I'm using Keras to build a convolutional neural net to perform regression from microscopic images to 2D label data (for counting). I'm looking into training the network on smaller patches of the microscopic data (where the patches are the size of the receptive field). The problem is, the fit() method requires validation data to be of the same size as the input. Instead, I'm hoping to be able to validate on entire images (not patches) so that I can validate on my entire validation set and compare the results to other methods I've used so far. One solution I found was to alternate between fit() and evaluate() each epoch. However, I was hoping to be able to observe these results using Tensorboard. Since evaluate() doesn't take in callbacks, this solution isn't ideal. Does anybody have a good way validating on full-resolution images while training on patches?

You could use fit generator instead of fit and provide a different generator for validation set. As long as the rest of your network is agnostic to the image size, (e.g, fully convolutional layers), you should be fine.

I can't comment on the question because of low rep, so using an answer instead. Can you clarify your question a bit, maybe with a small concrete example using very small tensors? What are the "columns" you are referring to? You say that you want to keep 50 columns (presumably 50 numbers) per image. If so, the (10, 50) shape seems like what you want - it has 50 numbers for each image in the batch. The (10, 50, 20, 3) shape you mention would allocate 50 numbers to each "image_column x channel". That is 20*3*50 = 3000 numbers per image. How do you want to construct them from the 50 that you have? Also, can you give a link to tf.batch_nd(). I did not find anything similar and relevant.

I have a tensor of shape (10, 100, 20, 3). Basically, it can be thought of as a batch of images. So the image height is 100 and width is 20 and channel depth is 3. I have run some computations to generate a set of 10*50 indices corresponding to 50 columns I would like to keep per image in the batch. The indices are stored in a tensor of shape (10, 50). I would like to end up with a tensor of shape (10, 50, 20, 3). I have looked into tf.batch_nd() but I can't figure out the semantics for how indices are actually used. Any thoughts?

Yes, that should work - I can't think of any issues that would prevent that approach from scaling to thousands of groups. However, be aware that Wagtail doesn't currently provide complete isolation between sub-sites on the same Wagtail installation - users will still be able to see pages from other groups when they're choosing a page to link to.

Scenario: A User registers to my Wagtail site. This creates a Group, and a Page. This page wil be set Private 'Private, accessible to users in specific groups' The just created group will be set.

The performance impacts are minimal. Importing a module the first time loads the module bytecode and objects into memory (stored in the sys.modules mapping). That loading will take a small amount of time, and a small amount of memory. You'd have to be a much larger project for that to start to matter. The Mercurial project, which cares deeply about start-up time (a command line client has to be responsive and fast), uses a lazy-loading scheme where imported module loading is deferred until actually accessed. This way the project can reference hundreds of modules (and extensions) but only actually load those that the current command line options require. The alternative would be for your own code to define the functionality, but executing the bytecode for that would also take time and memory, but with the added downside that you are likely to introduce bugs or make design mistakes that the standard library has managed to eliminate over the years.

I was recently thinking about standard libraries and using them in my programming. And I got to wondering about calling libraries, I hear a lot of talk on dependencies and managing them in order to not overload your program with unnecessary modules and whatnot. So I was wondering if there is additional load/increase in resource use when using functions and modules from the standard library. For instance, if I wrote a program that was entirely built of standard lib functions and none of my "own" code (meaning that I have a large amount of import statements), would I see a performance dropoff? Or is standard library loaded with every program, regardless of whether it's called or not? Hence it being part of the standard library. Thanks guys, happy to elaborate on my question if I haven't been clear enough.

Is there a penalty for using built in libraries in Python?

My json file is in the same directory of view.py file. However, when I open the html in browser, the IO error happens. When I run view.py through pycharm, it works fine. The JSon file is a database configuretion file. I want to display some data from the databse in that case I need to connect to database first.

With the information provided, it is really hard to give you a good answer. Howevr, I assume, that you run your view in PyCharm by actually running views.py instead of using the runserver command? In this case, the execution directory is the folder of your app and a relative path to the JSON file can be resolved. As soon as you run a development or real server and access the view in the browser using its URL, the execution directory is the firectory of the manage.py file (the root folder of your project). If you just access the name of your JSON file, then it cannot be found, since you are searching it in the wrong folder. What are you using the JSON file for? If it should be available in the web borwser as well (as a resource for e.g. JavaScript), then you may want to put it into the static folder of your app or project (remember to run manage.py collectstatic then). In this case, the STATIC_ROOT would be defined in settings.py and you could resolve the path from there (using os.path.join(STATIC_ROOT, "path to json file") )

Yes, you can move messages between queues within the same broker, or across brokers. Same broker use case: Application sends message to queue1 on brokerA. Using ActiveMQ's Composite Destination support, you could configure brokerA to also deliver the message to queue2 on brokerA. Different broker use case: Application sends message to queue1 on brokerA, the messages are then passed queue2 on brokerB using a bridge, or an ActiveMQ network connector. Additionally, code could read a message from queue1 on brokerA, perform some processing and then publish the message to queue2 on brokerB. As Tim mentioned in his comment, additional detail identifying which use case applies to you is needed in order to recommend the best solution.

Is it possible to share data between queues in stomp? We have a new project and my task is pass data from one queue to another. Consider a system with ActiveMQ and Stomp. In this system I have find a message that return by queue1 and pass to queue2. This doesn't make much sense to me. Any advice about this issue would be appreciated. Use Case: I have an application like this: queue1 : make query from ldap and find user queue2 : make query from exchange server with given user I want to use "user" founded from queue1 for query in queue2

Normally, IDLE has an Option / Configure IDLE menu which allows you to remap almost any action to a key combination. The newline and indent action is by default mapped to Key Return and Num Keypad Return, while Ctrl J is used for plain newline and indent. But it is easy to change this mapping configuration.

Recently my Enter key stopped working. For sure it's a hardware problem!. However I managed so many days without Enter key by using the alternatives ctrl + j or ctrl + m .Running python programs was fine as I would run the script by saving it in a file. Now that I need to give commandline values I have to press enter for it to be accepted in the IDLE Interpreter. While typing this too I can't press enter or ctrl + j or ctrl + m. But how did I do this? (This newline?) I copied a empty newline from another file. Even this doesn't work in the interpreter. Someone help any way to enter values in python IDLE Interpreter without actually using enter key. One good alternative would be to use the cmd or terminal and using the command line python script.py. And then using ctrl+m as this works there. But I miss the python interpreter. Any alternatives any suggestion? Ofcourse onscreen keyboard is an option but I'm looking for any key alternatives to enter in python Interpreter. Is that even possible?

Alternative for 'enter' key in python interpreter?

@Kevin Malachowski : Thanks for guiding me with your info and questions as It gave me new way of thinking. Historical data records will be more than 0.3-0.5 million(maximum). Now I'll use BigQuery for historical advance search. For live data-cloudSQL will be used as we must focus on perfomance for fetched data. Some of performance issue will be there for historical search, when a user wants both results from live as well as historical data. (BigQuery is taking time near about 5-6 sec[or more] for worst case) But it will be optimized as per data and structure of the model.

I'm using google cloudSQL for applying advance search on people data to fetch the list of users. In datastore, there are data already stored there with 2 model. First is used to track current data of users and other model is used to track historical timeline. The current data is stored on google cloudSQL are more than millions rows for all users. Now I want to implement advance search on historical data including between dates by adding all history data to cloud. If anyone can suggest the better structure for this historical model as I've gone through many of the links and articles. But cannot find proper solution as I have to take care of the performance for search (In Current search, the time is taken to fetch result is normal but when history is fetched, It'll scan all the records which causes slowdown of queries because of complex JOINs as needed). The query that is used to fetch the data from cloudSQL are made dynamically based on the users' need. For example, A user want the employees list whose manager is "[email protected]" , by using python code, the query will built accordingly. Now a user want to find users whose manager WAS "[email protected]" with effectiveFrom 2016-05-02 to 2017-01-01. As I've find some of the usecases for structure as below: 1) Same model as current structure with new column flag for isCurrentData (status of data whether it is history or active) Disadv.: - queries slowdown while fetching data as it will scan all records. Duplication of data might increase. These all disadv. will affect the performance of advance search by increasing time. Solution to this problem is to partition whole table into diff tables. 2) Partition based on year. As time passes, this will generate too many tables. 3) 2 tables might be maintained. 1st for current data and second one for history. But when user want to search data on both models will create complexity of build query. So, need suggestions for structuring historical timeline with improved performance and effective data handling. Thanks in advance.

Depending on how often you want to do live queries vs historical queries and the size of your data set, you might want to consider placing the historical data elsewhere. For example, if you need quick queries for live data and do many of them, but can handle higher-latency queries and only execute them sometimes, you might consider periodically exporting data to Google BigQuery. BigQuery can be useful for searching a large corpus of data but has much higher latency and doesn't have a wire protocol that is MySQL-compatible (although it's query language will look familiar to those who know any flavor of SQL). In addition, while for Cloud SQL you pay for data storage and the amount of time your database is running, in BigQuery you mostly pay for data storage and the amount of data scanned during your query executions. Therefore, if you plan on executing many of these historical queries it may get a little expensive. Also, if you don't have a very large data set, BigQuery may be a bit of an overkill. How large is your "live" data set and how large do you expect your "historical" data set to grow over time? Is it possible to just increase the size of the Cloud SQL instance as the historical data grows until the point at which it makes sense to start exporting to Big Query?

As @davidism suggested, Config files are never meant to be tracked since these are your secret keys and anybody with access to your code will have access to your keys if tracked. But, there is no hard and fast rule in Flask to keep your settings file in a specific location. You can keep them anywhere and name them anything. But, when adding the config to the app, the correct file path must be given.

There is no simple way. A listbox can only contain text. You can fake it fairly easily with a text widget, since a text widget allows you to embed widgets. For each row you could insert the text, insert a progress bar, and then insert a newline.

Using tkinter and .after, I wrote a little single-threaded program that displays 1000 ovals that move randomly across the screen, updating every 50ms, and I don't see any lag. At 10ms I think I maybe see a tiny bit of lag. These are simple objects with very little math to calculate the new positions, and there's no collision detection except against the edges of the window. The GUI seems responsive. I am able to type into a text window in the same GUI as fast as I can. I don't know how that compares to what you want to do.

I'm a bot developer but I'm new to Python. I've been reading for hours now, planning the design of a new bot. I'd like your opinion on performance issues with running a GUI and a very fast core loop to keep a modest array of game entities updated. The bot consists of a main array in an infinite loop which continually updates and also runs calculations. I know from my past bots that GUIs provide a problem with performance as they need to wait to detect events. I've looked at the possibility of a second thread, but I read that tkinter doesn't like more than one thread. I've checked out the idea of using .after to run the core array loop from the tkinter mainloop but my gut tells me that this would be bad practice. Right now I feel all I can do is try to contain the GUI and the core array all in one loop but this has never been good for performance. Are there better ways of designing the structure of this bot that I have not discovered? Edit I decided on removing the mainloop from tinker and simply using .update() to update any gui components I have, right now, this only consists of some labels which overlay the game screen. Both the labels and the bot's functions run great so far.

The .geometry() method of the root (or any Toplevel) window is your interface to its size and position. Call it with no parameters to get a geometry string; you can then call the method with that string to set the window to the same place on the screen. For example, I get '200x200+5+28' for a small window on my main monitor, '200x200+2592+414' after moving it to the monitor on the right. (This is on Mac OS X, conceivably it works differently on other platforms.)

For that specific command, you should not need any automation tool to feed input to your script. Piping a file to it should allow it to execute without user interaction (like Coldspeed said in his comment). Most command line interfaces allow parametrized execution and most parameters you can either build into your script or read them from a config file somewhere. For those command line tools that require "real" user interaction (i.e. you can't pipe the input, parametrize it or somehow build it into the command itself), I used the pexpect module with great success.

"The idea is to create a variety of methods that can be run by clicking a button and/or inserting content in inputs, and having the tests / functions run and returning the specified results." Maybe Flask can help you here. It has a nice functionality to route urls to specific functions or methods in your code. It provides a convenient way to bind actions to code. You can search the web for how you can leverage Flask to cater to your specific needs, but here I just wanted to convey that it would help.

In my opinion, If the functionality should be part of an object behavior and it's related only to that object than implement it as a method at the class scope, for example, only str should have functions like lower. When the function can be applied to a lot of class types like len can be applied on lists or on str than it should be a function.

What are the advantages of having a python method, like lower(), being applied to an appropriate object, s, via the dot notation (i.e., s.lower()) versus a method, like len(), being also applied appropriately receiving the object as an argument, e.g. len(s) ? If I want to create such a method / function, what are the critical points I should consider choosing the first or the second implementation? Thanks!

Any answer likely depends on the distro for which the rpm was built. A generic, albeit manual approach, would to start with rpm -q --requires $PACKAGE but as you already have the spec file, you can simply rpmspec -q --requires *spec to get that same info. Look for the packages providing Python resources, e.g., python3-requests. You'll need to translate each of these into the Python package name, e.g., 'requests' for your setup.py. You may find that rpm -q --provides python3-requests to be useful at this step; maybe not.

By default I had python-2.6 installed on my Centos. I installed python-3.6.1 and Pycharm IDE. When I open settings of my Pycharm I can't see new interpreter for python-3.6.1. How do I locate and add the new interpreter?

I am running some code with selenium using python, and I figured out that I need to dynamically change the UserAgent after I already created the webdriver. Any advice if it is possible and how this could be done? Just to highlight - I want to change it on the fly, after almost each GET or POST request I send

Requirements: Virtual Env Pycharm Go to Virtual env and type which python Add remote project interpreter (File > Default Settings > Project Interpreter (cog) add remote) You'll need to set up your file system so that PyCharm can also open the project. NOTE: do not turn off your virtual environment without saving your run configurations that will cause pycharm to see your run configurations as corrupt There's a button on the top right that reads share enable this and your run configs will be saved to a .idea file and you'll have a lot less issues

If you already have your virtualenv installed you just need to start using it. Create your projects virtual environment using virtualenv env_name on cmd. To associate a specific version of python with your environment use: virtualenv env_name -p pythonx.x; Activate your environment by navigating into its Scripts folder and executing activate. Your terminal now is using your virtual environment, that means every python package you install and the python version you run will be the ones you configured inside your env. I like to create environments with the names similar to my projects, I always use one environment to each project, that helps keeping track of which packages my specific projects need to run. If you haven't read much about venvs yet, try googling about requirements.txt along with pip freeze command those are pretty useful to keep track of your project's packages.

Yes, you can. You can filter by TCP port 80 (checking each packet or using BPF) and then check the TCP payload to ensure there is an HTTP header.

If you are looking at the date, you can say [25 Aug 2016] since openssl v1.1.0 is released as you mentioned. This is not a problem with the version of pyopenssl, but rather with the version of the openssl library you are using. Since pyopenssl, a wrapper library of openssl for python, doesn't modify openssl itself. so, if you are using openssl v1.1.0 or later, TLS v1.2 is the default, otherwise TLS v1.2 is not the default.

I want to know when exactly was it added that the default cipher selection would be TLSv1.2 ciphers while using the wrapper function of python's openssl. I was able to find this data in the changelog of openssl. It seems that even though TLSv1.2 support was added on 14th March, 2012, it was made a default option only on 25th August, 2016. Changes between 1.0.0h and 1.0.1 [14 Mar 2012] *) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based ciphersuites. At present only RSA key exchange ciphersuites work with TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods and version checking. Changes between 1.0.2h and 1.1.0 [25 Aug 2016] *) Changes to the DEFAULT cipherlist: - Prefer (EC)DHE handshakes over plain RSA. - Prefer AEAD ciphers over legacy ciphers. - Prefer ECDSA over RSA when both certificates are available. - Prefer TLSv1.2 ciphers/PRF. <--- - Remove DSS, SEED, IDEA, CAMELLIA, and AES-CCM from the default cipherlist. [Emilia Käsper] [Steve Henson] But this is for the openssl library. For pyopenssl, the changelog seems less detailed, there is an update and version release (version 16.1.0) just after a day (on 26th August, 2016), but they have not mentioned this detail. And I am not able to find a mention of which exact version of openssl is the pyopenssl using in the changelog history.

When was TLSv1.2 ciphers were added as a default selection while using python's openssl module

Me and my group are currently working on a school project where we need to use an online python compiler, since we are not allowed to install or download any software on their computers. The project requires me to read data from a .xlsx file. Is there any online IDE with xlrd that can read the file that is on the school's computer? I've been looking at a few but can't seem to find any that has this support. On tutorialspoint.com it is possible to upload the excel file but not import xlrd. Other sites has xlrd but doesn't allow for uploading files to the site.

Could the pandas package and its pandas.read_clipboard function help? You'd need to copy the content of the file manually to the clipboard before starting your script. Alternatively - is it considered cheating to just rent a server? Pretty cheap these days. Finally: you don't usually require admin rights to install Python... so assuming it's not a violation of school policy, the Anaconda distribution for instance is very happy to be installed for the local user only.

A simple solution to this (which does work) would be to use Powershell as an Administrator, instead of cmd. Conversely, use cmd as an administrator, though I would recommend using the much-more powerful Powershell for any and all purposes! Why this works: A lot of commands need super-user rights (think root/ sudo in linux) in order to be properly executed. Since there is no such thing as as sudo in Windows yet, you can implement it via admin privileges. Cheers!

I tried to set up a virtual environment for my project by executing virtualenv myenv. The folder seemed to be generated, but the command hung, and I couldn't execute another command. I had to close the console and restart cmd. The folder was generated, as I said, but I couldn't activate the virtual environment by venv\Scripts\activate. I met the same behaviour while trying to execute pip freeze > requirements.txt. The file was generated, but it was empty, although I used a lot of packages in my project. When I executed just pip freeze, the list of packages was printed, but the command hung again, and I had to close the console again. I tried both procedures many times, but with no success. I tried that in Windows cmd and Anaconda Prompt (Anaconda version: Anaconda3 2.4.1; Python: 3.5.1). EDIT: when I tried to do this for the very first time some days ago, I succeeded in activating the virtual environment, but only for one time.

Use pip freeze > requirements.txt to save a list of installed packages. Create a new venv with python 3.6. Install saved packages with pip install -r requirements.txt. When pip founds an universal wheel in its cache it installs the package from the cache. Other packages will be downloaded, cached, built and installed.

Because Sphinx imports the module, it does not seem to find the local copy, but rather imports the older version already installed on my system, and uses that to generate the docs. Running python setup.py install, and then regenerating everything finally worked.

I am trying to use Sphinx to create simple documentation for a python module. The first time I ran it, it worked fine. Now I have made some updates to the module, and rerunning the documentation commands: $ sphinx-apidoc -P -F -f -e -o . /path/to/module $ make html it always uses the old version of the python module code. I have tried deleting the entire docs directory, moving the module, rechecking it out, updating sphinx - nothing works. The old code is still being reused and cached somewhere. It is driving me absolutely insane.

Sphinx is caching python module somewhere: WHERE?

I will answer since I don't satisfied with the accepted answer. Probably because I don't use IDLE. Note that, I use Ubuntu (terminal). Probably in other OSs, it works the same. Is there a way to install that? No need. I found that it comes by default. How to access that? Use help() command in python' shell. In the shell, type command help(). Now that you're in the help utility, enter anything that you want to read its documentation. Press q to quit the documentation and type quit to quit the help utility.

For elementwise multiplication it does not matter, and flattening the array does not change a thing. Remember: Arrays, no matter their dimension, are saved linearly in RAM. If you flatten the array before multiplication, you are only changing the way NumPy presents the data to you, the data in RAM is never touched. Multiplying the 1D or the 100D data is exactly the same operation.

I'm working with multidimensional matrices (~100 dimensions or so, see below why). My matrix are NumPy arrays and I mainly multiply them with each other. Does NumPy care (with respect to speed or accuracy) in what form I ask it to multiply these matrices? I.e. would it make sense to reshape them into a linear array before performing the multiplication? I did some own test with random matrices, and it seemed to be irrelevant, but would like to have some theoretical insight into this. I guess there is a limit to how large matrices can be and how large they can be, before Python becomes slow handling them. Is there a way to find this limit? I have several species (biology) and want to assign each of these species a fitness. Then I want to see how these different finesses affect the outcome of competition. And I want to check for all possible fitness combinations of all species. My matrices have many dimensions, but all dimensions are quite small.

Multiprocessing is generally for when you want to take advantage of the computational power of multiple processing cores. Multiprocessing limits your options on how to handle shared state between components of your program, as memory is copied initially on process creation, but not shared or updated automatically. Threads execute from the same region of memory, and do not have this restriction, but cannot take advantage of multiple cores for computational performance. Your application does not sound like it would require large amounts of computation, and simply would benefit from concurrency to be able to handle user input, networking, and a small amount of processing at the same time. I would say you need threads not processes. I am not experienced enough with asyncio to give a good comparison of that to threads. Edit: This looks like a fairly involved project, so don't expect it to go perfectly the first time you hit "run", but definitely very doable and interesting. Here's how I would structure this project... I see effectively four separate threads here (maybe small ancillary dameon threads for stupid little tasks) I would have one thread acting as your temperature controller (PID control / whatever) that has sole control of the heater output. (other threads get to make requests to change setpoint / control mode (duty cycle / PID)) I would have one main thread (with a few dameon threads) to handle the data logging: Main thead listens for logging commands (pause, resume, get, etc.) dameon threads to poll thermometer, rotate log files, etc.. I am not as familiar with networking, and this will be specific to your client application, but I would probably get started with http.server just for prototyping, or maybe something like websockets and a little bit of asyncio. The main thing is that it would interact with the data logger and temperature controller threads with getters and setters rather than directly modifying values Finally, for the keypad input, I would likely just make up a quick tkinter application to grab keypresses, because that's what I know. Again, form a request with the tkinter app, but don't modify values directly; use getters and setters when "talking" between threads. It just keeps things better organized and compartmentalized.

I am trying to build a temperature control module that can be controlled over a network or with manual controls. the individual parts of my program all work but I'm having trouble figuring out how to make them all work together.also my temperature control module is python and the client is C#. so far as physical components go i have a keypad that sets a temperature and turns the heater on and off and an lcd screen that displays temperature data and of course a temperature sensor. for my network stuff i need to: constantly send temperature data to the client. send a list of log files to the client. await prompts from the client to either set the desired temperature or send a log file to the client. so far all the hardware works fine and each individual part of the network functions work but not together. I have not tried to use both physical and network components. I have been attempting to use threads for this but was wondering if i should be using something else? EDIT: here is the basic logic behind what i want to do: Hardware: keypad takes a number inputs until '*' it then sets a temp variable. temp variable is compared to sensor data and the heater is turned on or off accordingly. '#' turns of the heater and sets temp variable to 0. sensor data is written to log files while temp variable is not 0 Network: upon client connect the client is sent a list of log files temperature sensor data is continuously sent to client. prompt handler listens for prompts. if client requests log file the temperature data is halted and the file sent after which the temperature data is resumed. client can send a command to the prompt handler to set the temp variable to trigger the heater client can send a command to the prompt handler to stop the heater and set temp variable to 0 commands from either the keypad or client should work at all times.

should i be using threads multiprocessing or asycio for my project?

I'm trying to run a python script that uses a custom module written by someone else. I created that module by running CMake according to the creator's instructions. Running my python script, I get the error: ImportError: libopencv_imgproc.so.3.1: cannot open shared object file: No such file or directory. This error is caused by the module I created earlier. There is no file of that name since I have OpenCV 3.2.0 installed, so in usr/local/lib there's libopencv_imgproc.so.3.2.0. I don't know how to fix this or where to start looking. The CMakeLists.txt of the module has a line find_package(OpenCV 3 COMPONENTS core highgui imgproc REQUIRED). I tried changing it to find_package(OpenCV 3.2.0 COMPONENTS core highgui imgproc REQUIRED), without success.

How can I force CMake to use the correct OpenCV version?

Will mainloop() continually update while it waits for another button press, or will I essentially have to creatre an update method that cycles through everything until another button is pressed? Not all. That's why you are using tk.Tk().mainloop(). tkinter does this for you. All you are expected to do is implement the functionality that should happen when your button is pressed. tkinter will listen for the button press.

So I was wondering if someone would be able to help shed a little light for me on something I am working on in Python. I am creating a program with a Tkinter GUI interface that interacts with a Serial device, and an ADC chip to measure voltage. I want to make sure I properly understand how I'm building the main program loop to keep everything running smoothly. I'm going to lay out how I think the program should run, if anyone has any corrections please throw them at me. Program is run, GUI Interface initializes User presses a button send signal of button through serial measure/display voltage levels periodically update voltage display if button is pressed, return to step 3 Now I know to run my Tkinter GUI I set up mainloop() as the last line of code. Now my question is simply, is that all I will need? Will mainloop() continually update while it waits for another button press, or will I essentially have to creatre an update method that cycles through everything until another button is pressed?

Want Clarification for Program Loop (Python)
