[mod_python] global variables are not made global?

i'm so embarrassed, i cant write python I'm sorry. I made sure that I knew
how to do imports before I emailed here, but actually when i tried it i did
it just like you, with main.a and import main. However in my actual code for
mod_python I do from main import *, and then i tried to refer to a, just
normally without any prefix like in main.a. And it turns out that you cant
do that, it won't work. Sorry about that. Thank you very much for your help.
