this might help:

"global" is used in a local scope to tell Python that something isn't a
local variable; see

    http://www.python.org/doc/faq/programming.html#how-do-you-set-a-global-variable-in-a-function
    http://www.python.org/doc/faq/programming.html#what-are-the-rules-for-local-and-global-variables-in-python

and

    http://docs.python.org/ref/naming.html

for details.
