Is it possible to create C-style "main" function in Python? (for teaching purposes)

I never have this concern either.  Python's functions and classes are
powerful enough to avoid globals entirely.  In C I have a few sometimes
and in Fortran and the like they're everywhere.  Global variables are
POWERFUL and USEFUL but there's a certain paradigm that goes with them,
and Python works better with an object-oriented w/ functional elements
approach.
