Just think of the "global" statements as the declarations you've
always wanted in Python.  It's not really much of a step down, since
you have to declare variables in Pascal anyways.

Python encourages good programming practive by considering all
variables local until proven global.  Meanwhile, other languages
beginning with "P" that shall remain nameless encourage poor
programming by considering all variables global until declared local.

As others have said, preceded by an underscore is most common.
