Re: Use of statement 'global' in scripts.

The statement 'global', indicating variables living in the global scope, is very suitable to be used in modules. I'm wondering whether in scripts, running at the top-level invocation of the interpreter, statement 'global' is used exactly the same way as in modules?

The 'global' statement declares a name to be module-level, so there's no
reason to use it at the top level of either a script or a module, since
everything there is module-level anyway.
You only need it if you want to assign to a module-level name from
within a function, e.g.
spam = 17
def f():
   global spam
   spam = 42
f()
# spam is now 42
A script is a module, so everything that applies to modules also
applies to scripts.
