Just wanted to know:
If I create a game using python and pygame, how can I make it usable on an internet site like facebook without needing the user to have python?

As far as I know, Python cannot be compiled, and the end-user will have to have the Python interpreter. That is different than the tools you had to download to develop with it, though. It is not really any different than needing .NET for running C# or Visual Basic programs, the JVM for running Java, Flash plugin for running Flash content, etc. People are pretty used to it.

I dont imagine a lot of people haveing Python tho or can even find where to get the interpretor...so i guess it would be pointless to show off my work that way. Im really just looking for a way to show my work and get more ideas for what to program in order to continue to improve my coding skills lol.

Actually, I found a couple of things here:

Py2exe lets you actually compile your Python applications to run natively under Windows. Mac and Linux are not a problem since they come with the Python interpreter already installed.

Here is a conversation about almost the same question on the Stack Overflow forums. They give links to several different solutions.

You can also find more info by Googling "deploying Python applications". "Deploy" is the jargon for distributing applications to end-users, and if you weren't using the term in web searches, it may have been the cause of not finding meaningful results.

thank you very much Jack! that was very helpful...Indeed there are many solutions which I can use.

If you're creating a game for Facebook or some other social media site, the code is entirely on the back end. For Facebook, specifically, you will write your program to generate Facebook Markup Language (FBML) which is then processed by Facebook.

The end user does not need Python on their machine to use your app.

Google "Python FBML" for more information on how to create your Facebook app in Python.
