Python Tutorial 02: Adding a background

In the first tutorial, we created a simple window using Python and Pygame. The next step, will be building on that example, we will create a star field background, then write the code to animate it.  One important point about these tutorials is the assumption that anyone following along already has at least a basic knowledge of how Python code is structured.  If that is not the case, then you should, at the very least, want to have the Python documentation(included in the Python install) at hand incase you wanted it for a reference.  There are some very good resources available for Python, either through THE OFFICIAL PYTHON WEB-SITE or by completing a Google search on the Python version you have installed.  If you have already coded the first tutorial you should do just fine with this one.  If there are any comments about the tutorials, whether they are critical or complimentary, you’re welcome to post them.  If there’s information that I have glossed over or skipped entirely, let me know, and I will add it in, with future edits of the tutorials.

NOTE:

I typically use Editra v0.7.12 to write Python code, when including the psyco try/except block, Editra would occasionally crash.  When I ran the starfield.py file in Python IDLE 2.6, it never crashed(but you need to have the pygame.quit() statement, so the app window does not crash).  If you’re using a different IDE your mileage may vary, if in doubt, use IDLE as your benchmark(or use IDLE to run this example).

UPDATE: Psyco is no longer supported as of March 12, 2012. If you are already using it you can choose to include it, if you’re not using psyco then avoid the install unless your confident that you can make it work.

Skip the source code in red, it is the psyco try/except block!
