I've seen numerous ways of retrieving installed programs on WinXP+ in python. What is the proper and most robust way of doing this? Currently I'm accessing HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall and reading each of the keys from there to get a list. (I've been told this isn't the proper way of doing things) I've...
I've created a model in one of my apps which works fine. However, I needed to add a new field. I did this, and used manage.py reset <appname> to drop the tables and add them again. This process went fine - the new field appears in the database. However, I can't get the field to show up in the admin interface, nor in the custom model form...
One of the great features of Django is that you can open a python interpreter set-up for use with your project. This can be used to analyse objects in a database and allows any python commands to be executed on your project. I find it essential for Django development. It is invoked in the project directory using this command: $ python m...

Relatively new to Python, and I saw the following construct in the PyFacebook library (source here: http://github.com/sciyoshi/pyfacebook/blob/master/facebook/init.py#L660). I'm curious what this does because it appears to be a class that inherits from itself. class AuthProxy(AuthProxy): """Special proxy for facebook.auth.""" ...

I'm looking to create a search function for my flash game website. One of the problems with the site is that it is difficult to find a specific game you want, as users must go to the alphabetical list to find one they want. It's run with Google App Engine written in python, using the webapp framework. At the very least I need a simple...
I would like to pass some options to Python (version 2.6) every time, not just in interactive mode. Is there a file I can put such commands in? EDIT: Specifically, I'm wanting to silence the Deprecation warnings. ...

No specific programming language, except the library or the software has to work really well. I found various libraries for PHP and Python, but most of it hasn't been updated or being maintained and don't work for various manufact...
Hey guys, sorry but this is going to be a big one.. ;) I'm running into an annoying little snag right now. I'm creating an RSS-style app for work which will be placed on some large LCD displays across the office. The basic concept is to have a client/server setup where the user would use a custom editor to create the individual articles...
Hello, I've begun playing around with OpenGL in Python using PyOpenGL 3.0.1b. I looked at some sample code and started running it and modifying it etc. All was well until I became a little less ignorant. On http://pyopengl.sourceforge.net/documentation/manual-3.0/index.xhtml the OpenGL functions are listed as well as whether or not th...
After several hours of working on porting this program over, it appears to finally be in a working state. However, I was wondering if anyone knew of a better way or more complete way of porting Java servlets over into Python. The beginning of the Python script contains a lot of support code to make it easier to port the program line-by-l...
I have a custom class with a serialize method, and I want to be able to write this class directly to files and have the return value of the serialize method get written, in Python 2.6. (I'm not trying to pickle my objects, this is something totally different.) For example: class Foo(object): def serialize(self): return "Hel...

I'm writing a simple forum-like application on Google App Engine and trying to avoid scalability issues. I'm new to this non-RBDMS approach, i'd like to avoid pitfalls from the beginning. The forum design is pretty simple, posts and replies will be the only concepts. What will be the best approach to the problem if the forum have million...
Here is the situation. I have a django project with two installed apps. Both apps appear to function properly if they are installed independently of each other. However if I list both apps in the settings.INSTALLED_APPS the reverse() function seems to break for urls in the first app. So this leads me to believe that a bug in the seco...
