You shouldn't -- it sets up the worst possible kinds of
dependencies.  But if you're really dead set on it:

===spam.py:

taste = 23

import eggs


===eggs.py:

import __main__

print __main__.taste



and run "python spam.py".  This will allow you to write
a real disaster of an undebuggable, unmaintainable
multi-module program.
