Short answer : never !-)
Long answer:
First point: "global" really means "module level" - there's no
"application global" namespaces.
Second point: every name declared as the top-level is global - according
to the above definition. So there's no need to declare them as such. The
only place where you need the global statement is when you want to
rebind a module-level name from within a function. And it's in this
function that you need to declare the name as global.
FWIW, this is documented.
Last point: Python is not C, and it definitively doesn't have pointers.
Trying to write C in Python is a waste of time and an experiment in
frustration (just like trying to write language XXX in language YYY for
any distinct values of XXX and YYY).
