How can I, when a user clicks a link, open a div right underneath the link which loads it's content via AJAX? Thanks for the help; I cannot find out how to. Just statically filling the div on the server side while loading the page works fine, but it's too much content for that. I'm kind of looking for a specific Django version of the...

Just wondering how many people use a path module in Python such as Jason Orendorff's one, instead of using os.path for joining and splitting paths? Have you used: Jason's path module (updated for PEP 355) Mike Orr's Unipath, basically a more modern version of the above Noam Raphael's alternative path module that subclasses tuple instea...
I have a friend who I have been trying to help learn computer programming and I have a question on his behalf. He's interested in doing some biological modeling for his own research and needs to visualize his data using graphical elements, but he needs more power than can be found in Excel or similar solutions. I naturally sent him to Py...
I have a class that calls traceback.extract_stack() in its __init__(), but whenever I do that, the value of traceback.extract_stack() is []. What are some reasons that this could be the case? Is there another way to get a traceback that will be more reliable? I think the problem is that the code is running in Pylons. Here is some co...
I have python .egg files that are stored in a relative location to some .py code. The problem is, I am targeting python 2.5.1 computers which require my project be self contained in a folder (hundreds of thousands of OLPC XO 8.2.1 release laptops running Sugar). This means I cannot just ./ez_install to perform a system-wide setuptools/...

When using subprocess.Popen(args, shell=True) to run "gcc --version" (just as an example), on Windows we get this: >>> from subprocess import Popen >>> Popen(['gcc', '--version'], shell=True) gcc (GCC) 3.4.5 (mingw-vista special r3) ... So it's nicely printing out the version as I expect. But on Linux we get this: >>> from subprocess...
Since I am working with different Platforms and programming languages, I found there are many good libraries that are ported with different programming language than its original. For example JUnit and Log4j which has been ported into several different languages. Sometimes if I am already used to working with these libraries, I would fin...
I am writing a website which intends to be a place for use to paste/answer coding questions. Especially Python. So, I am looking for an "online judge" engine that could support Python(c/c++/java/# could be a plus), so that the guy who paste the question could provide a simple test, then others could answer it with the onlinejudge to ver...
I'm trying to transfer a transfer a function across a network connection (using asyncore). Is there an easy way to serialize a python function (one that, in this case at least, will have no side affects) for transfer like this?

Hello, I am considering programming the network related features of my application in Python instead of the C/C++ API. The intended use of networking is to pass text messages between two instances of my application, similar to a game passing player positions as often as possible over the network.
