I don't start off with a main function, but if my script gets long and complicated, or if global names have proliferated and have become confusing, I'll refactor the whole thing into functions, including a "main". With most globals moved into main's namespace, calling subroutines from main forces me to define the context that's actually necessary for each part of the program. The resultant refactored programs are much easier to test, read and maintain. TLDR: "Called-only-once" functions like main are useful as documentation, hooks for testing, and for unraveling a snarl of global variables. -- Neil Cerutti -- http://mail.python.org/mailman/listinfo/python-list
