Well, *I* don't go around defining global variables, but there are times
when they are the way to go. For example, if a module function uses a
regular expression, the regular expression should be compiled into a
(module) global variable.
Module functions and classes are global variables as well:
>>> import math
>>> def f(x): return -1
...
>>> math.sqrt = f
>>> math.sqrt(3)
-1
