You have to add the Python directory (C:\Python24) to your PATH 
environment variable. There are some directions here:

I don't think you have to do that. If you open your file in an editing 
window you can run from there with Run / Run Module (F5). If you are 
importing into the shell window you can use Shell / Restart Shell to 
clear any imports, or use reload(<module>) to get a fresh copy.

I don't know what you mean by this, what is a default module?
