That way you also have the chance to inject complete custom editors into Maya via scriptedPanels.
But if you're bound to Python, pyQt is the way to go. | 2 | 8 | 0 | I develop tools in Autodesk Maya. Many of the tools I build have simple windowed GUIs for the animators and modellers to use. These GUIs often contain what you'd normally expect to see in any basic window; labels, lists, menus, buttons, textfields, etc. However, there are limitations to the complexity of the UIs you can build with the available tools, specifically in the types of available widgets.
I'm interested in using some of the more advanced wxPython widgets such as the ListView (grid), Tree, etc. This would involve using a complete wxFrame (window) to display the whole UI, which would essentially mean that window would no longer be tied to Maya. Not a deal breaker, but it means when Maya is minimized, the window won't follow suit.
I've tried something like this before with tkinter as a test, but found that it needed a MainLoop to run in its own thread. This is logical, but in my case, it conflicts with Maya's own thread, essentially making Maya hang until the window is closed. This is due to the fact that Maya runs all scripts, be they MEL or Python, in a single thread that the main Maya GUI shares. This is to prevent one script from, say, deleting an object while another script is trying to do work on the same object.
wxPython has this same "mainloop" methodolgy. I'm wondering if there's any way around it so that it can work within Maya? | Using external GUI libraries to make user interfaces in Autodesk Maya | 0 | 0 | 0 | 3,503 |

But there are several means of inter-process communication, like pipes or semaphores. Maybe it is an option to split your Maya extension into the actual plugin, being tight into maya, and a separate application for the gui. These two could use such means to communicate and exchange model information between plugin and gui.
I'm not sure, however, if I can really recommend this approach because it very much complicates the application.
You could have a look at IPython, an interactive Python shell, whose dev team has put some effort into integrating it with wxPython. They have some way of interrupting the event loop and hooking into it to do their own stuff. | 2 | 8 | 0 | I develop tools in Autodesk Maya.

import time
time.sleep(2)
will not work for waiting 2 seconds between requests | 3 | 18 | 0 | I'm working on a Python library that interfaces with a web service API. Like many web services I've encountered, this one requests limiting the rate of requests. I would like to provide an optional parameter, limit, to the class instantiation that, if provided, will hold outgoing requests until the number of seconds specified passes.
I understand that the general scenario is the following: an instance of the class makes a request via a method. When it does, the method emits some signal that sets a lock variable somewhere, and begins a countdown timer for the number of seconds in limit. (In all likelihood, the lock is the countdown timer itself.) If another request is made within this time frame, it must be queued until the countdown timer reaches zero and the lock is disengaged; at this point, the oldest request on the queue is sent, and the countdown timer is reset and the lock is re-engaged.
Is this a case for threading? Is there another approach I'm not seeing?
Should the countdown timer and lock be instance variables, or should they belong to the class, such that all instances of the class hold requests?
Also, is this generally a bad idea to provide rate-limiting functionality within a library? I reason since, by default, the countdown is zero seconds, the library still allows developers to use the library and provide their own rate-limiting schemes. Given any developers using the service will need to rate-limit requests anyway, however, I figure that it would be a convenience for the library to provide a means of rate-limiting.
Regardless of placing a rate-limiting scheme in the library or not, I'll want to write an application using the library, so suggested techniques will come in handy. | How to limit rate of requests to web services in Python? | 0.033321 | 0 | 1 | 17,294 |

I would suggest keeping all the variables within the instance, so you can easily implement multiple periods/rates of control.
Lastly, it sounds like you want to be a middleware component. Don't try to be an application and introduce threads on your own. Just block/sleep if you are synchronous and use the async dispatching framework if you are being called by one of them. | 3 | 18 | 0 | I'm working on a Python library that interfaces with a web service API.

A simpler solution is to give your class a variable for the time the service was last called. Whenever the service is called (!1), set waitTime to delay - Now + lastcalltime. delay should be equal to the minimum allowable time between requests. If this number is positive, sleep for that long before making the call (!2). The disadvantage/advantage of this approach is that it treats the web service requests as being synchronous. The advantage is that it is absurdly simple and easy to implement.
(!1): Should happen right after receiving a response from the service, inside the wrapper (probably at the bottom of the wrapper).
(!2): Should happen when the python wrapper around the web service is called, at the top of the wrapper.

I started by getting a list of all python-related files, ordered by date, on the assumption that all of the files in my package will have more or less the same timestamp, and no other files will.
Luckily, I've got python installed under /opt/Python-2.6.1; if I had been using the Python that comes with my Linux distro, I'd have had to scour all of /usr, which would have taken a long time.
Then I just examined that list, and noted with relief that all the stuff that I wanted to nuke consisted of one directory, /opt/Python-2.6.1/lib/python2.6/site-packages/module-name/, and one file, /opt/Python-2.6.1/lib/python2.6/site-packages/module-x.x.x_blah-py2.6.egg-info.
So I just deleted those.
Here's how I got the date-sorted list of files:
find "$@" -printf '%T@ ' -ls | sort -n | cut -d\ -f 2-
(I think that's got to be GNU "find", by the way; the flavor you get on OS X doesn't know about "-printf '%T@'")

Find or if necessary define by yourself the method that does what you want for any possible type of input and just call it without asking about anything. If you need to work with built-in types or types defined by a third-party library, you can always inherit from them and use your own derivatives instead. Or you can wrap them inside your own class. This is the object-oriented way to resolve such problems.
If you insist on checking exact type and placing some dirty ifs here and there, you can use __class__ property or type function to do it, but soon you will find yourself updating all these ifs with additional cases every two or three commits. Doing it the OO way prevents that and lets you only define a new class for a new type of input instead. | 3 | 2,000 | 0 | How do I see the type of a variable?

You have products and barcodes. Products are uniquely identified by Product Code (e.g. 'A2111'; barcodes are uniquely identified by Value (e.g. 1002155061).
A Product has a Barcode. Questions: Can a product have no barcode? Can the same product have multiple barcodes? Can multiple products have the same barcode? (If you have any experience with UPC labels, you know the answer to all these is TRUE.)
So you can make some assertions:
A Product (code) has zero or more Barcode (value).
A Barcode (value) has one or more Product (code). -- assumption: we barcodes don't have independent existence if they aren't/haven't been/won't be related to products).
Which leads directly (via your ORM model) to a schema with two tables:
Product
ProductCode(PK) Description etc
ProductBarcode
ProductCode(FK) BarcodeValue
-- with a two-part natural primary key, ProductCode + BarcodeValue
and you tie them together as described in the other answers.
Similar assertions can be used to determine which fields go into various tables in your design. | 2 | 0 | 0 | I'm wondering, is it possible to make an sql query that does the same function as

Ruby is more flexible in the Perl way and you can do a lot of hacks; Python is targeted towards readability, which is a very good thing, and generally language hacks are a little frowned upon. Ruby's basic types can be modified in a hackish way that typically prototype languages allow, while Python's basic types are more suited for subclassing.
By the way, I would add a minor correction: both Ruby and Python are very, very object-oriented, and neither is intended to be used for quick-and-dirty scripts the Perl way.

Python is a good language and I enjoy working with it too, but I think Ruby is somewhat more Lispy in the degree of freedom it gives to the programmer. Python seems to impose its opinions a little bit more (which can be a good thing, but isn't according to our criteria here).
Python certainly isn't more Perlish— Ruby is essentially a Smalltalk/Perl mashup (some of its less-used features are pulled directly from Perl), whereas Python is only distantly related to either. | 6 | 21 | 0 | I am a C++ developer, slowly getting into web development.

But Ruby is very nearly a clone of Smalltalk (and I hope will grow more like Smalltalk as the Perlish cruft is deprecated), and Smalltalk, like Lisp, is a language that takes one idea to extremes.

The two languages both grant a nice amount of leeway when it comes to programming paradigms, but are also have benefits/shortcomings. I think that the compromises you make either way are a lot about your own programming style and taste.
Personally, I think Ruby can read more like pseudo-code than Python. First, Python has active whitespace, which while elegant in the eyes of many, doesn't tend to enter the equation when writing pseudo-code. Also, Ruby's syntax is quite flexible. That flexibility causes a lot of quirks that can confuse, but also allows code that's quite expressive and pretty to look at.
Finally, I'd really say that Ruby feels more Perl-ish to me. That's partly because I'm far more comfortable with it, so I can hack out scripts rather quickly. A lot of Ruby's syntax was borrowed from Perl though, and I haven't seen much Python code that feels similar (though again, I have little experience with Python).
Depending on the approach to web programming you'd like to take, I think that the types of web frameworks available in each language could perhaps be a factor in deciding as well. I'd say try them both. You can get a working knowledge of each of them in an afternoon, and while you won't be writing awesome Ruby or Python, you can probably establish a feel for each, and decide which you like more.
Update: I think your question should actually be two separate discussions: one with Ruby, one with Python. The comparisons are less important because you start debating the merits of the differences, as opposed to which language will work better for you. If you have questions about Ruby, I'd be more than happy to answer as best I can. | 6 | 21 | 0 | I am a C++ developer, slowly getting into web development.

Python had a few libraries that i wanted to try out and Perl didn't, so I went with Python. In the end, none of those libraries were useful to me but besides library support I prefer python personally anyway so that was the right decision.
Because your question is very vague I can only suggest that you don't use PHP and select the language based on library support for your specific problem area and your comfort in that language.

In the Expando documentation it says:
Tip: If you want to validate a dynamic property value using a Property class, you can instantiate the Property class and call its validate() method on the value.
So if I want to validate a dynamic property I need to know what the class's non-dynamic properties are. How can I ask my class what it's defined properties are?
I've considered creating a class method that takes a string and returns true if that string is in a list of property names that I create and maintain, but it seems like a hack. I've searched the Google for tips, but haven't had any luck.

Remember that pretty much everything in Python is a name referring to an object, and nothing gets copied in usual operation.
If you didn't have to explicitly specify when an identifier was to refer to a predefined global, then you'd presumably have to explicitly specify when an identifier is a new local variable instead (for example, with something like the 'var' command seen in JavaScript). Since local variables are more common than global variables in any serious and non-trivial system, Python's system makes more sense in most cases.
You could have a language which attempted to guess, using a global variable if it existed or creating a local variable if it didn't. However, that would be very error-prone.

Its ability to interoperate painlessly with Objective C frameworks is superb. I have less experience with Ruby Cocoa and that was partly because when I last looked it didn't seem to have as clean and relatively painless interoperability. I feel hesitant about MacRuby because it seems to go too far. In pyobjc you can write plain python and only subclass/use Foundation and Cocoa objects when you really want/mean to. From what I understand of MacRuby it is a Ruby on top of Cocoa. So a string is always an NSString. I am less happy with that.

This appears to make the interpreter prepared to re-import the same modules even though it has already imported them before.
The module-reload-forcing approach can be made to work in some circumstances but it's a bit hairy. In summary:
You need to make sure that all modules that have dependencies on each other are all reloaded at once. So any module 'x' that does 'import y' or 'from y import ...' must be deleted from sys.modules at the same time as module 'y'.
This process will need protecting with a lock if your app or any other active module is using threads.
Any module that leaves hooks pointing to itself in other modules cannot usefully be reloaded as references to the old module will remain in unreloaded/unreloadable code. This includes stuff like exception hooks, signals, warnings filters, encodings, monkey-patches and so on. If you start blithely reloading modules containing other people's code you might be surprised how often they do stuff like that, potentially resulting in subtle and curious errors.
So to get it to work you need to have well-defined boundaries between interdependent modules - "was it imported at initial start-up time" probably isn't quite good enough - and to make sure they're nicely encapsulated without unexpected dependencies like monkey-patching.
This can be based on folder, so for example anything in /home/me/myapp/lib could be reloaded as a unit, whilst leaving other modules alone - especially the contents of the stdlib in eg. /usr/lib/python2.x/ which is in general not reliable to reload. I've got code for this in an as-yet-unreleased webapp reloading wrapper, if you need.
Finally:
You need to know a little bit about the internals of sys.modules, specifically that it leaves a bunch of 'None' values to signify failed relative imports. If you don't delete them at the same time as you delete your other module values, the subsequent attempt to import a module can (sometimes) end up importing 'None', leading to confusing errors.
This is a nasty implementation detail which might change and break your app in some future Python version, but that is the price for playing with sys.modules in unsupported ways. | 4 | 7 | 0 | I have a python interpreter embedded inside an application.

I doubt this is actually 100% true. If the overall application is the result of an act of Congress, okay, it can't be changed.

I'm just wondering how I should go about structuring this...
Do I create a class and make each box a object of that class (9x9=81 objects)? If yes, how do I control all the objects - in other words, how do I make them all call a certain method in the class?
Do I just create functions to calculate and just control all the numbers in there with something like an multi-D array?

Another class will be used to solve the puzzle. | 5 | 0 | 0 | I'm trying to create a sudoku solver program in Java (maybe Python).

Known calls; those with a fixed value, no choices.
Unknown cells; those with a set of candidate values that reduces down to a single final value.
Second, there are several groups of cells.
Horizontal rows and Vertical columns which must have one cell of each value. That constraint is used to remove values from various cells in the row or column.
3x3 blocks which must have one cell of each value. That constraint is used to remove values from various cells in the block.
Finally, there's the overall grid. This has several complementary views.
It's 81 cells.
The cells are also collected into a 3x3 grid of 3x3 blocks.
The cells are also collected into 9 columns.
The cells are also collected into 9 rows.
And you have a solver strategy object.
Each Unknown cell it set to having set( range(1,10) ) as the candidate values.
For each row, column and 3x3 block (27 different collections):
a. For each cell:
If it has definite value (Known cells and Unknown cells implement this differently): remove that value from all other cells in this grouping.
The above must be iterated until no changes are found.
At this point, you either have it solved (all cells report a definite value), or, you have some cells with multiple values. Now you have to engage in a sophisticated back-tracking solver to find a combination of the remaining values that "works". | 5 | 0 | 0 | I'm trying to create a sudoku solver program in Java (maybe Python).

It's a 2-D array or maybe a Board class that represents a 2-D array at best. Have functions that calculate a given row/column and functions that let you access each square. Additional methods can be used validate that each sub-3x3 and row/column don't violate the required constraints. | 5 | 0 | 0 | I'm trying to create a sudoku solver program in Java (maybe Python).

Depending on how long your sessions last, and how big your database is, you might want to cleanup more often than once per day. But one cleanup pass per day is usually fine. | 3 | 1 | 0 | I'm writing a webapp that will only be used by authenticated users. Some temporary databases and log files will be created during each user session. I'd like to erase all these temp files when the session is finished.
Obviously, a logout or window close event would be sufficient to close the session, but in some cases the user may keep the browser open long after he's finished.
Another approach would be to time user sessions or delete the temp files during routine maintenance.
