When you do something like "hi".print(), you are implying that the string object "hi" has a method print. This is not the case. Instead, print is a function that takes a string (or other types) as input.
| 3 | 7 | 0 |
My understanding of the print() in both Python and Ruby (and other languages) is that it is a method on a string (or other types). Because it is so commonly used the syntax:
print "hi"
works.
So why doesn't "hi".print() in Python or "hi".print in Ruby work?
|
Why can't I "string".print()?

I have a string and I need match that string with an sequence and determine the number of times the matched sequence is found in that sequence
But it has following conditions
Sequence can contain only ACGT valid chars so seq could be ACGTGTCTG
the string could be ACGnkG
where n could be replaced by A or G
k could be replaced by C or T
how can we find if the string matches the sequence by substituting valid values for n and k
Is there any regular expression ?

Python uses a linear list layout in memory so that indexing is fast (O(1)).
| 2 | 15 | 0 |
Just learning Python. Reading through the official tutorials. I ran across this:
While appends and pops from the end of list are fast, doing inserts or pops from the beginning of a list is slow (because all of the other elements have to be shifted by one).
I would have guessed that a mature language like Python would have all sorts of optimizations, so why doesn't Python [seem to] use linked lists so that inserts can be fast?

list is implemented as an arraylist. If you want to insert frequently, you can use a deque (but note that traversal to the middle is expensive).
Alternatively, you can use a heap. It's all there if you take the time to look at the docs.

Now, I want to host my application in the web. I heard WSGI is the best way to expose Python/Django application to the web? What would be the best way to expose Python/Django code into the web? Thank you
P.S: I already have a domain name and a shared web hosting from justhost.com. While I chat to their support, they told me that they support WSGI.

A simple approach is to build the minimum spanning tree for your graph and do a (depth-first) walk over it, skipping nodes already visited.
This is proven to be no more than twice as long as the optimal TSP path. You can definitely do better with heuristics, but it's a starter (and easy to implement too).
| 1 | 4 | 0 |
My problem is the following:
I have an undirected graph. Each edge has a cost (or weight). One of the nodes is labelled S. I want to start from S and visit every node at least once. Visiting a node multiple times is allowed. Travelling along an edge multiple times is allowed, although that would make the solution more expensive -- travelling an edge with cost of 3 twice will add 6 to the cost of the total path. The graph has some "dead-end" nodes, so sometimes we have to travel an edge more than once.
What is a fast algorithm to do this? Is this a well known problem?
What I'm looking for:
Reasonably fast -- The relative size of the graph we are talking about here is order of 40 - 50 nodes. So the algorithm hopefully won't take longer than 10 - 15 seconds.
Reasonably optimal -- I'm not looking for absolute optimality. Any interesting heuristic to guide the search so that the solution will be near optimal is good enough.
I will be writing this in python. So if you know of any python implementation of the algorithm, that's best.
Thanks for any help.

This seems to happen if you have async operations in progress before you enter the ndb.toplevel function.
My guess is that this warns you that theses async operations will not be waited for at the end of the request. This could be an issue if you expected them to be included in your "toplevel" function and they are tasklets waiting for an operation to complete before executing some more.

Is this a warning of some sort? Should it be ignored? It doesn't cause any unusual behavior.

Override fail() to generate the screenshot and then call TestCase.fail(self)?

I have some class-based unit tests running in python's unittest2 framework. We're using Selenium WebDriver, which has a convenient save_screenshot() method. I'd like to grab a screenshot in tearDown() for every test failure, to reduce the time spent debugging why a test failed.
However, I can't find any way to run code on test failures only. tearDown() is called regardless of whether the test succeeds, and I don't want to clutter our filesystem with hundreds of browser screenshots for tests that succeeded.
How would you approach this?

Unless you're being really careful, serializing the entire object into redis is going to cause problems. You're effectively treating it like a cache, so you have to be careful that those values are expired if the user changes something about themselves. You also have to make sure that all of the values are serializable (likely via pickle). You didn't specify whether this is a premature optimization so I'm going to say that it probably is and recommend that you just track the user id and reload his information when you need it from your database.
| 1 | 1 | 0 |
I have a few a few model classes such as a user class which is passed a dictionary, and wraps it providing various methods, some of which communicate with the database when a value needs to be changed. The dictionary itself is made from an sqlalchemy RowProxy, so all its keys are actually attribute names taken directly from the sql user table. (attributes include user_id, username, email, passwd, etc)
If a user is logged in, should I simply save this dictionary to a redis key value store, and simply call a new user object when needed and pass it this dictionary from redis(which should be faster than only saving a user id in a session and loading the values again from the db based on that user_id)?
Or should I somehow serialize the entire object and save it in redis? I'd appreciate any alternate methods of managing model and session objects that any of you feel would be better as well.
In case anyone is wondering I'm only using the sqlalchemy expression language, and not the orm. I'm using the model classes as interfaces, and coding against those.

The session is basically a dictionary. Adapters are the values you can put into it, and interfaces are the keys you use with them.
Subclassing comes with a bunch of problems, none of them specific to the web or session state handling. It mixes lots of implementation concerns together that don't need to be mixed. A dictionary, on the other hand, is just a collection of state - exactly what is called for when it comes to tracking the state needed for a session.
Your alternate idea, to "just subclass or wrap the session and use this subclass to generate sessions" is very general and somewhat ambiguous, so I can't explain in detail why the current system might be better than it. If you want to describe your idea in complete detail (perhaps by providing an implementation), then perhaps someone can critique it.

It feels to me that using components/adapters is just adding extra bloat to handling sessions without much obvious benefit. It feels simpler to just subclass or wrap the session and use this subclass to generate sessions.
Maybe I am not seeing some obvious benefits of using components and adapters, so if anyone could explain this to me, please do.

Documentation for win32com is next to non-existent as far I know. However, I use the following method to understand the commands.
MS-Excel
In Excel, record a macro of whatever action you intend to, say plotting a chart. Then go to the Macro menu and use View Macro to get the underlying commands. More often than not, the commands used would guide you to the corresponding commands in python that you need to use.
Pythonwin
You can use pythonwin to browse the underlying win32com defined objects (in your case Microsoft Excel Objects). In pythonwin (which can be found at \Lib\site-packages\pythonwin\ in your python installation), go to Tools -> COM Makepy Utility, select your required Library (in this case, Microsoft Excel 14.0 Object Library) and press Ok. Then when the process is complete, go to Tools -> COM Browser and open the required library under Registered Libraries. Note the ID no. as this would correspond to the source file. You can browse the various components of the library in the COM Browser.
Source
Go to \Lib\site-packages\win32com\ in your python installation folder. Run makepy.py and choose the required library. After this, the source file of the library can be found at \Lib\site-packages\win32com\gen_py . It is one of those files with the wacky name. The name corresponds to that found in Pythonwin. Open the file, and search for the commands you saw in the Excel Macro. (#2 and #3 maybe redundant, I am not sure)

Hi I intend to draw a chart with data in an xlsx file.
In order to keep the style, I HAVE TO draw it within excel.
I found a package named win32com, which can give a support to manipulate excel file with python on win32 platform, but I don't know where is the doc.....
Another similar question is how to change the style of cells, such as font, back-color ?
So maybe all I wanna know is the doc, you know how to fish is more useful than fishes.... and an example is better.

playOrm supports JOIN on noSQL so that you CAN put relational data into noSQL but it is currently in java. We have been thinking of exposing a S-SQL language from a server for programs like yours. Would that be of interest to you?
The S-SQL would look like this(if you don't use partitions, you don't even need anything before the SELECT statement piece)...
PARTITIONS t(:partId) SELECT t FROM TABLE as t INNER JOIN t.security as s WHERE s.securityType = :type and t.numShares = :shares")
This allows relational data in a noSQL environment AND IF you partition your data, you can scale as well very nicely with fast queries and fast joins.
If you like, we can quickly code up a prototype server that exposes an interface where you send in S-SQL requests and we return some form of json back to you. We would like it to be different than SQL result sets which was a very bad idea when left joins and inner joins are in the picture.
ie. we would return results on a join like so (so that you can set a max results that actually works)...
tableA row A - tableB row45
- tableB row65
- tableB row 78
tableA row C - tableB row46
- tableB row93
NOTICE that we do not return multiple row A's so that if you have max results 2 you get row A and row C where as in ODBC/JDBC, you would get ONLY rowA two times with row45 and row 65 because that is what the table looks like when it is returned (which is kind of stupid when you are in an OO language of any kind).
just let playOrm team know if you need anything on the playOrm github website.

I won't go so far as to say it's impossible, but this is an extremely tall order. The reason is that an HTML parser will usually not attempt to preserve HTML-irrelevant characters like line endings, but anything other than an HTML parser will not be very good at telling what is or isn't a tag according to the strict definitions of the format.
If you really need to do this and do this well, I would look at dissecting an existing python HTML parser and modifying it to your needs. This is a fairly advanced programming project. It would be better to seriously consider why you need to do this and if this is strictly the right thing to do.
Edit: An additional problem is that it's not really possible to parse HTML without checking the validity of the HTML and either reforming it to be valid, or choking on invalid HTML. So if you potentially have validity problems with your HTML, your result is undefined. For instance, if the input includes a grossly invalid tag like <font="courier">, would that be considered an HTML tag for the purposes of this exercise, or just a string of parser-killing characters? Likewise with a valid-looking tag in the wrong place in the document.

pySerial uses the native OS drivers for serial receiving. In the case of Windows, the size of the input driver is based on the device driver.
You may be able to increase the size in your Device Manager settings if it is possible, but ultimately you just need to read the data in fast enough.

I want to communicate with the phone via serial port. After writing some command to phone, I used ser.read(ser.inWaiting()) to get its return value, but I always got total 1020 bytes of characters, and actually, the desired returns is supposed to be over 50KB.
I have tried to set ser.read(50000), but the interpreter will hang on.
How would I expand the input buffer to get all of the returns at once?

I'm guessing that you are reading 1020 bytes because that is all there is in the buffer, which is what ser.inWaiting() is returning. Depending on the baud rate 50 KB may take a while to transfer, or the phone is expecting something different from you. Handshaking?
Inspect the value of ser.inWaiting, and then the contents of what you are receiving for hints.

I ended up creating a table with a single row, updated to contain the latest valid token.
Main reason: I know that wherever I deploy this application, and no matter how many processes across how many machines are serving, the database will work as storage. It's not that much extra code either, and goes well with Django's application packaging.

I'm running a Django app that needs to interact with an external API to make requests in behalf of its users.
Before making any calls, I have to obtain an access token through an OAuth-like interface. This token is mine, my users won't have one each. I have tested the entry points and methods with curl, and everything seems to work fine, so I'm ready to integrate the service.
How should I go about requesting, storing, reusing and renewing this token when it expires? Also, which parts of the process should run on the client's browser, and which parts on the Django backend?

Nope, python dicts will not see any difference in what characters you use in the key string.
They are optimized to deal with strings only versus arbitrary key objects, but if you use only string values for keys you won't see any difference between using keys without and with non-alphanumeric characters.
The string-only codepath is an optimization for the most common usecase for python dicts: namespaces and function definitions. This is the default mode for a dict; as soon as you store a non-string key in it, the lookup method is switched and you'll have a teensy-weensy slower dict on your hands. This won't matter much in most Python applications though.

I use Windows XP and Python 2.5. I am trying to make a way for my python programs to secretly communicate with each other, I think the STARTUPOPTIONS class could hide the window, but I can't find out how I could communicate with them. On my python subprocess I tried using raw_input and on the parent I tried writing to the Popen.stdin and flushing it, but it diden't seam to work. I would use Popen.communicate, but that waits for the process to exit. Is there a way to do this? Thanks!
EDIT:
I am going to only make my program available for windows users so if there is a module that is only available for windows, I will not mind it can't run on other Operating Systems.

There is no one-size-fits-all answer to this
Dividing a big task A into many small parts (A¹, A², A³, …) will increase potential concurrency.
So if you have 1 worker instance with 10 worker threads/processes,
A can now run in parallel using the 10 threads instead of sequentially
on one thread.
The number of parts is called the tasks granularity (fine or coarsely grained).
If the task is too finely grained the overhead of messaging will drag performance down.
Each part must have enough computation/IO to offset the overhead of sending the task
message to the broker, possibly writing it to disk if there are no workers to take it, the worker to receive the message, and so on (do note that messaging overhead can be tweaked, e.g. you can have a queue that is transient (not persisting messages to disk), and send tasks that are not so important there).
A busy cluster may make all of this moot
Maximum parallelism may already have been achieved if you have a busy cluster (e.g. 3 worker instances with 10 threads/processes each, all running tasks).
Then you many not get much benefit by dividing the task, but tasks doing I/O have a greater chance of improvement than CPU-bound tasks (split by I/O operations).
Long running tasks are fine
The worker is not allergic to long running tasks, be that 10 minutes or an hour.
But it's not ideal either because any long running task will block that slot from
finishing any waiting tasks. To mitigate this people use routing, so that you have a dedicated queue, with dedicated workers for tasks that must run ASAP.

In my solution I use distributed tasks to monitor hardware instances for a period of time (say, 10 minutes). I have to do some stuff when:
I start this monitoring session
I finish this monitoring session
(Potentially) during the monitoring session
Is it safe to have a single task run for the whole session (10 minutes) and perform all these, or should I split these actions into their own tasks?
The advantages of a single task, as I see it, are that it would be easier to manage and enforce timing constraints. But:
Is it a good idea to run a large pool of (mostly) asleep workers? For example, if I know that at most I will have 200 sessions open, I have a pool of 500 workers to ensure there are always available "session" seats?

If you're looking to learn new things, and aren't looking to make a "must work today" type project, try Python3. It will be easier to move forward into the future with Python3, as it will become the standard over time.
If you're making something quick and dirty, you'll typically get better library support with Python 2.7.
Finally, if anything you are using includes full unicode support, don't sell yourself short -- go with Python3. The simplification of unicode alone is worth it.

Nowadays, quite a number of libraries support Python 3. There is not a single list of these, so you'll have to check the frameworks you'd like to use for Python 3 compatibility. Some support Python 3 only in some beta stage, but that doesn't mean those are bad.
I would start off nowadays with Python 3, and see where you get. Only if you know you need to support whatever you are developing on other platforms that you don't control, it may be better to start with Python 2.

Well it is purely your logic in the code. When you receive the message you are simply broadcasting it, what you have to do is to pass this onto a custom function, and there, do a check:
Create a temporary array that contains list of active authenticated users. when user logs on, it should send this special string, match it, if OK, add this user to this active user list array, if not don't add it. Later, call the bradcast function but rather then taking all online users, use this custom array instead.
That is all that you have to do.
Make sure when someone logs out, remove him from this array.

After the request object has gotten to the view it's recommended that you do not pass "as-is" to any non-web-specific code. Any code dealing with databases, etc shouldn't be coupled to pyramid's concept of a request. This pattern is easier to follow in Pyramid as it avoids a global request object.
The request object encompasses everything about why your view is being invoked, and making more code than necessary coupled to that object will cause you to write functions further down the pipeline that perhaps do "too much".

You could add a keystroke event listener and simply listen to the backspace keypress event.
When that happens, save and ajax the form field value to your server for storage.
EDIT: On basis of Scott Selby's anser:
To cover all bases:
Event listener for keypress backspace
Event listener for selection start and end. Save and ajax the selected part if if the form field has changed on the next keypress.
Catch onunload event, safe form data if exists.
That way you always get what the users deleted. This also helps making your search query window "typo" proof because you'll be able to spot "common" mistakes over time.
It's also a good way to collect data on what products or services your potential clients expect from you.

I'm using Jquery autocomplete on an input field. So, as users type out a word, they can see a drop-down list showing fewer and fewer choices to select from.
The thing is, sometimes the user's input will not be among the choices in that list. I believe that when users see that list go empty, they will give up on their original search term and either enter a different one, or simply delete it and leave the field blank.
When that happens, I want to know what was the original search term entered?
(Because after collecting that info over time, I plan to add the most popular ones to the list, for future users to choose from)
So my question is, what is the best way to find out what users typed in, but didn't submit?
My idea so far is to listen for when the user takes the focus off the input field, and get it's value on change. That will tell me about users who deleted and left it blank, but it still doesnt tell me anything for the users who deleted and then entered a new term.
Is there a better solution?
PS - My site is on GAE, so if using python opens any relevant doors... there's that too.

Not 100% clear on what you mean by 'make a video'. You can run use mencoder if say you do not like using ffmpeg for some reason.
Whatever that may be, you need a video source and video encoder to generate a video. Of course you could write your own video encoder in python if you wanted but that would leave you doing only that for next few months and it would run very slowly.
You need a raw YUV input to encode or another stream to transcode and 'make a video'. The input can come from a hardware or a file or stream on a socket.

It would be nice if the program was compatible with PIL or pygame images, but if not I could probably work around that.

In the end, it depends on the level of security you need.

I have couple of apps on internet and want to serve static files for those apps using another Django App. I simply can't afford to use Amazon Web Services for my pet-projects.
So, I want to setup an Admin interface where I can manage static files easily. The following are the actions I am thinking to include in admin.
Upload, delete static files
Grouping static files (creating new folders, adding new/ existing files to it); I am not sure If it is possible.
checking my models
Thus, I would like to know how secure is Django-Admin interface!
How secure it is when compared to our famous sites like Yahoo, Facebook, Google Login's.. (at least in terms of "cracking".. is django admin can be cracked easily?)

Besides serving static files through django is considered a bad idea, the django admin itself is pretty safe. You can take additional measure by securing it via .htaccess and force https access on it. You could also restrict access to a certain IP. If the admin is exposed to the whole internet you should at least be careful when choosing credentials. Since I don't know how secure Google and Yahoo really are, I can't compare to them.

How long ago did you create your DNS TXT record? Since DKIM is a DNS controlled service, and DNS often takes up to days to propagate across the Internet, you may need to wait for that to happen before Google will recognize it as valid.
| 1 | 0 | 0 |
Am confused why emails sent by my appengine app are not being signed with DKIM.
Enabled DKIM signing on Google Apps dashboard. Confirmed that my domain is "Authenticating email"
Have setup DNS TXT record using the values indicated in the apps domain. Have confirmed, using 3rd party validation tool, that the DNS is correct. Also, I assume that having a green-light indicator for authenticating email in my Google Apps domain means this record has been validated by Google Apps.
Email-send is being triggered by a click by a user browsing my application via my custom url. The custom url matches the domain for the return address of the sender. The sender return address is an owner of the account.
As far as I know, these are the requirements for emails to be signed automatically. Yet, alas, they are not being signed. Any help or ideas will be greatly appreciated. Thanks -

You have Apache 2.2 core package installed, but possibly have the devel package for Apache 1.3 instead of that for 2.2 installed. This isn't certain though, as for some Apache distributions, such as when compiled from source code, 'apxs' is still called 'apxs'. It is only certain Linux distros that have changed the name of 'apxs' in Apache 2.2 distros to be 'apxs2'. This is why the mod_wsgi configure script checks for 'apxs2' as well as 'apxs'.
So, do the actual make and see if that fails before assuming you have the wrong apxs.

Counter is a good way to do this, but Counter is only available in 3.1 and up, plus 2.7.
If you're on 3.0 or 2.[56], you probably should use collections.defaultdict(int) instead.

You're confusing things a bit.
The only thing stored inside "Django's session cookie" is an ID. That ID refers to the data which is stored inside the session backend: this is usually a database table, but could be a file or cache location depending on your Django configuration.
Now the only time that data is updated is when it is modified by Django. You can't expire data automatically, except by either the cookie itself expiring (in which case the entire set of data persists in the session store, but is no longer associated with the client) or by running a process on the server that modifies sessions programmatically.
There's no way of telling from the server end when a user leaves a website or closes his browser. So the only way of managing this would be to run a cron job on your server that gets sessions that were last modified (say) two hours ago, and iterate through them deleting the data you want to remove.

I am going to be storing a significant amount of information inside Django's session cookie. I want this data to persist for the entire time the user is on the website. When he leaves, the data should be deleted, but the session MUST persist. I do not want to user to need to log in every time he returns to the website.
I found ways to purge the entire session cookie every time a user leaves the website, but ideally I would like to only delete select pieces of the cookie which I explicitly set. Does anyone know how to do this?

I suggest that you run your code in some sort of editor (pretty much any will do: Eclipse, Geany, Spyder, IDLE, etc.). The reason for this is that when the program is executed, you are most likely getting a fatal error in your code somewhere. Python IDEs have a tendency to keep the windows used to execute the code open even if there is an error, so you can see the error callback for reference. That will tell you where you are getting the error, and will allow you to fix the code accordingly. of course, you could always just tack on input() or time.sleep() to the end and hope that helps, but that's up to you. I recommend using an IDE like one I mentioned above.

I have that issue with python interpreter - it's closing immediately after script execution. I'm trying to learn pygtk; I wrote "hello world" after tutorial and all I can see is a quick flash of two windows, one interpreter's and one gtk's. I tried to run the script from command.com instead of by double-click - didn't help much.
In older Windows I'd simply check the checkbox on apropriate tab, but how do I do it on this frelling eye candy?

Here are some suggestions:
Save the user preferences/settings on the Server too, so that you can have their preferences synced to multiple clients/devices in the future.
Having the data stored locally on the client is also recommended, so that the calls are not made to the server everytime to get some preferences. In offline situations, having the relevant data available locally within the client is very critical.
In terms of Storage options on GAE - there are various ones. Since you are using Datastore I suggest that you go with that. In terms of storage size of each entity and in/out bandwidth, it is something that you can calculate approximately and if you feel that you can achieve the same logic via a few numbers or combined number (in a single Datastore entity attribute) rather than multiple entity attributes, it is preferable and will help.

I want to minimize traffic/storage costs on GAE.
Users fill out a form, checking boxes to select options which are lines of text, eg "I wake up two or more times during the night." or "I sleep less than 7 hours per night." or "I usually have trouble falling asleep."
I want to store the user's selections using the datastore. I suppose I can save on storage space by giving each selection a unique identifier. Then I'll just store (for example) "342, 554, 106" instead of three long lines of text... Then retrieve those numbers and translate them back into sentences next time loading the page for each user.
My question is, will it be better to do that conversion on the client side, or the server side?
Obviously, doing the conversion on the client side will mean sending LESS data from client to server for storage - which is good. However, it would mean sending MORE data from server to client, considering the additional lines of client-side javascript necessary to facilitate the conversion, which they will be downloaded as part of the page source - and that could be bad.

Sounds like you already figured out how best to store the data.
In terms of translating it to HTML on the server or client side, it'll depend on the complexity of your page. Analyzing it will probably be more time than it's worth, and it might change if your page changes. It's most likely a wash unless it's an extreme situation. Use whichever is simpler and get your project done and out the door. If you're using a framework that handles generating forms on the server side, use that. If you have hundreds of thousands of views and it's adding up to a significant cost, revisit the pages in particular that are causing you the problem.
An extreme situation might be if your form needs to appear many, many times on a page, in which case it may be easier to have the actual form in javascript once and reproduce it many many times.

Python is a "dynamically-typed" programming language, that meaning that the odds are against the IDE in providing code-intelligence.
That said, Wing-IDE is the very best for Python, and there are a few things you can do: first be sure to have open the "Source Assistant" panel, i.e., press F2 and locate it to your right. Second, be sure to inform the IDE of what Python interpreter are you using, as well as any particular Python path that your project might be using; all of that you can do in Project/Project Properties. Finally, you still might need to give hints sometimes to the IDE about your instances with "assert isinstance(x,SomeType)".
Admittedly, is not as straightforward as using Visual Studio, but the good reasons to use Python and its very capable ecosystem, or the easy integration with C/C++ more than compensate.

The communication with your server can be totally independent of the languages used on the server and client end.
Typically web applications use principles such as REST to communicate. This is why your browser runs using HTML and JavaScript and your server can be using anything, including python.
It really depends on what you need your server to do for your app.

In my case, I need to be able to match all alpha-numerical characters except numbers.

I need to use the special sequence \w because I'm dealing with non-ASCII characters and need to match symbols like "Æ" and "Ø".

So in short, how can I mix (add/subtract) special sequences in Python Regular Expressions?
EDIT: I accidentally used [\W^\d] instead of [\w^\d]. The latter does indeed match something, including parentheses and commas which are not alpha-numerical characters as far as I'm concerned.

I assume you use some library like urllib to do the scraping. You already know the website's content changes dynamically. I also assume that the dynamic content uses server-side interaction. This means, using javascript (ajax) the browser requests new data from the server, based on the value from the selection).
If so, then you could try to emulate the ajax call to the server in your web scraping library.
First, using a browser debugging tool find out the url to the server that is being invoked.
Split the parameters parts in the ajax call
Perform the same call to lookup the options in the select tag.

I want to scrape a webpage that changes its content via a <select> tag. When I select a different option, the content of the page dynamically changes. I want to know if there is a way that I can change the option from a python script so I can get the content from all different pages of all different options in <select> tag.

As @Tichodroma said, when the select is changed, either:
Some content previously hidden on the page is made visible, or:
An ajax call is made to retrieve some additional content and add it to the DOM
In both cases, JavaScript is involved. Have a look at it, and depending on what is happening (case #1 or #2), you should:
Scrape the whole page, since all the content you want is already in it, or:
Make several calls to the file usually called using ajax to retrieve the content you want for each value of the <select>

My python script does some heavy computation. To boost performance, it caches the computed data on the disk so that next time I'll run it, it doesn't waste time in computing the same thing. However, before extracting data from the cache, it needs to do some checking to make sure that the cache is not stale. This is the part where I am stuck.
My first idea was to compare the creation time of cache and modification time of python script and if the later is larger (ie more recent) than the former, I would consider the cache as stale, else not. However, since linux kernel does not store creation times of files, I am stuck at this point.
Similar situation:
When python interpreter creates .pyc files from .py files, it does something similar --> creates a new .pyc file if I'll modify my .py file after the .pyc file was created, else it does not. How does it do that? I wish to know the algorithm. Thank you.

Just check the last-modified time of your cache file instead.
Even better, that's what you really want to check in any case, because when you update your cache to store the new computed value, you want to know when that was done last, not when that was done the first time. :-)

I post here a schematic approach how to solve your problem with out any real python code, it might help though.
When actually plotting you need to store all in some kind of two lists, which will enable you to access them later.
For each element, bar and marker you can get the color.
For each marker you can find if it overlapping or inside a bar, for example you could usenxutils.pntpoly() [point in polygon test] from matplotlib itself.
Now you can decide on the best color. If you know the color of the bar in RGB format you can
calculate the completing color of the marker using some simple rules you can define.
When you got the color use the method set_color() or the appropriate method the object has.
| 1 | 1 | 1 |
I am using matplotlib to draw a bar chart with many different colors. I also draw a number of markers on the plot with scatter.
Since I am already using many different colors for the bars, I do not want to use a separate contrasting color for the marks, as that would add a big limit to the color space I can choose my bars from.
Therefore, the question is whether it is possible to have scatter draw marks, not with a given color, but with a color that is the inverse of the color that happens to be behind any given mark, wherever it is placed.
Also, note that the marks may fully overlap bars, partly overlap bars, or not overlap a bar at all.

Backdrop: Am building a shopify app using a test store provided by shopify. #Python #Django-
Problem: I have setup shopify webhooks for my test store using the python API for the topics "products/update" and "products/delete". But my endpoints are not called by shopify when I manually update or delete a product on my test store.
My detective work so far: I have checked the following:
I have confirmed that the webhooks were successfully created using the API. I simply listed all the existing webhooks using the API for the store and mine are there.
The address/URL I specified in the webhook for shopify to call in the event of a product update or delete is a public url, as in it is not on my localhost. (not 127.0.0.1:8000 etc.)
My webhook endpoint is fine. When I manually call my endpoint in a test case, it does what it should.
I contacted the shopify apps support guys, and I was asked to post this issue here.
Another minor issue is that I cannot find in the shopify API docs exactly what JSON/XML the webhook will POST to my URL in the event it should. So I do not know what that JSON will look like...
Any help would be appreciated!

I don't have the creds to comment apparently, so I'll put this in an "answer" - to use the term very loosely - instead. I ran into something similar with the Python API, but soon realized that I was doing it wrong. In my case, it was toggling the fulfillment status, which then fires off an email notifying customers of a download location for media.
What I was doing wrong was this: I was modifying the fulfillment attribute of the order object directly. Instead, the correct method was to fetch / create a fulfillment object, modify that, point the order attribute to this object, than save() it. This worked.
I don't know if this is your issue as there's no code posted, but I hope this helps.

Set represents a collection of distinct elements. In python, sets are mainly used for two reasons (Book: Data Science from Scratch, Joel Gruce):
For faster operation: in is a very fast operation on sets. If we have a large collection of elements and if we wish to perform membership test, in that case it is appropriate to use set instead of a list.
To find a distinct items in a collections. Programmers use sets much less frequently than dicts and lists.

Some more differences are:
List can be 2-D whereas a set can't.
As list are ordered (IE. have serial number) list are comparatively slow to execute whereas sets are fast.
List in python is like Array of java or c.
Printing a set almost always provide different sequence of output.
Set uses hash function to find an element whereas list is an array. Hence finding element in Set is faster than in list.

An SQL database should work fine in your case. In fact, you can store all the training examples in just one database, each row representing a particular training set and each column representing a feature. You can add features by adding collumns as and when required. In a relational database, you might come across access errors when querying for your data for various inconsistency reasons. Try using a NoSQL database. I personally user MongoDB and Pymongo on python to store the training examples as dicts in JSON format. (Easier for web apps this way).

I recommend using tensors, which is multidimensional arrays. You can use any data table or simply text files to store a tensor. Each line or row is a record / transaction with different features all listed.

Trying to set up some basic data I/O scripts in python that read and write from a local sqlite db. I'd like to use the command line to verify that my scripts work as expected, but they don't pick up on any of the databases or tables I'm creating.
My first script writes some data from a dict into the table, and the second script reads it and prints it.
Write:
# first part of script creates a dict called 'totals'
import sqlite3 as lite
con = lite.connect('test.db')
with con:
cur = con.cursor()
cur.execute("DROP TABLE IF EXISTS testtbl")
cur.execute("CREATE TABLE testtbl(Date TEXT PRIMARY KEY, Count INT, AverageServerTime REAL, TotalServerTime REAL, AverageClientTime REAL, TotalClientTime REAL)")
cur.execute('INSERT INTO testtbl VALUES("2012-09-08", %s, %s, %s, %s, %s)' % (float(totals['count()']), float(totals['serverTime/count()']), float(totals['serverTime']), float(totals['totalLoadTime/count()']), float(totals['totalLoadTime'])))
Read:
import sqlite3 as lite
con = lite.connect('test.db')
with con:
cur = con.cursor()
cur.execute("SELECT * FROM testtbl")
rows = cur.fetchall()
for row in rows:
print row
These scripts are separate and both work fine. However, if I navigate to the directory in the command line and activate sqlite3, nothing further works. I've tried '.databases', '.tables', '.schema' commands and can't get it to respond to this particular db. I can create dbs within the command line and view them, but not the ones created by my script. How do I link these up?

You say that you have a list of widgets to change dynamically. Do you want to reuse and reconfigure existing widgets, or create all new widgets and delete the old ones? It affects the answer.
If you want to reuse the existing widgets, just reconfigure them. Or, if you just want to hide some of them temporarily, use the corresponding "forget" method to hide them. If you mapped them with pack() calls, you would hide with pack_forget() (or just forget()) calls. Accordingly, grid_forget() to hide gridded widgets, and place_forget() for placed widgets.
If you do not intend to reuse the widgets, you can destroy them with a straight destroy() call, like widget.destroy(), to free up resources.

Pretty sure you are running into the HRD feature where queries are "eventually consistent". NDB's caching has nothing to do with this behavior.
| 1 | 2 | 0 |
So I have been reading a lot of documentation on HRD and NDB lately, yet I still have some doubts regarding how NDB caches things.
Example case:
Imagine a case where a users writes data and the app needs to fetch it immediately after the write. E.g. A user creates a "Group" (similar to a Facebook/Linkedin group) and is redirected to the group immediately after creating it. (For now, I'm creating a group without assigning it an ancestor)
Result:
When testing this sort of functionality locally (having enabled high replication), the immediate fetch of the newly created group fails. A NoneType is returned.
Question:
Having gone through the High Replication docs and Google IO videos, I understand that there is a higher write latency, however, shouldn't NDB caching take care of this? I.e. A write is cached, and then asynchronously actually written on disk, therefore, an immediate read would be reading from cache and thus there should be no problem. Do I need to enforce some other settings?

I'm thinking certain common words would be excluded (a, the, and, etc) and maybe the 10 longest words or just random not common words would be added to a form field like "tag1, tag2, tag3"

Is it possible to automatically pull random "tags" from a long string of text?

Of course it's possible, you pretty much described the algorithm to test, and it doesn't seem to contain any obviously non-computable steps:
Split the message into words
Filter out the common words
Sort the words by length
Pick the top ten and present them as tags
Not sure what you mean by "scalable level", this sounds client-side to me. Unless the messages are very long, i.e. not typed in by a human, I don't think there will be any problems just doing it.

IMAP server is still imap.gmail.com -- try with that?

I am trying to download emails using imaplib with Python. I have tested the script using my own email account, but I am having trouble doing it for my corporate gmail (I don't know how the corporate gmail works, but I go to gmail.companyname.com to sign in). When I try running the script with imaplib.IMAP4_SSL("imap.gmail.companyname.com", 993), I get an error gaierror name or service not known. Does anybody know how to connect to a my company gmail with imaplib?

I think I am too late to answer this question but anyways here goes nothing.
I have run in to the same problem before and I think there are two alternative solutions you can choose from.
using sleep(_sometime)
from time import *
sleep(10)
using a prompt message (note that I am using python 2.7)
exit_now = raw_input("Do you like to exit now (Y)es (N)o ? ")'
if exit_now.lower() = 'n'
//more processing here
Alternatively you can use a hybrid of those two methods as well where you can prompt for a message and use sleep(sometime) to delay the window closing as well. choice is yours.
please note the above are just ideas and if you want to use any of those in practice you might have to think about your application logic a bit.

I have just started college and we are going to be using python. We really have done nothing so I have downloaded the program and done some print commands, and that's it.
When I run my .py file (a print command) it immediately closes after appearing. I understand why it does this - it's given the output, so it's done what it needs to do - but I also understand that you can stop this from happening.
I looked around this website and none of the solutions given to this question worked, either that or I didn't understand them.
Is there a simple command I can input to my IDLE editor that will put the program on hold or something? I have tried input("prompt: ") as suggested by someone, and that made no difference.
If there isn't a command for this, is there a way to change the settings on the computer so that programs don't auto close?

Late in here, but in case someone comes here from google---
Go to the location of your .py file. Press SHIFT then right click anywhere and choose open command prompt from here. Once it's up, Just add
"python NameOfTheProg.py" to the cmd line

Well I got similar issue,
It is solved by adding Environment Variable.
Add System Variables in Window
Name : PYTHONPATH
Value : C:\Python27;
Your Python path.

Very simple:
Open command prompt as an administrator.
Type python.exe (provided you have given path of it in environmental variables)
Then, In the same command prompt window the python interpreter will start with >>>
This worked for me.

The reason why it is closing is because the program is not running anymore, simply add any sort of loop or input to fix this (or you could just run it through idle.)
