Why are you reading Python 2.4 docs? Try http://docs.python.org/ref/global.html The first sentence (which hasn't changed since 2.4) describing the global statement seems clear enough to me: "The global statement is a declaration which holds for the entire current code block." -- http://mail.python.org/mailman/listinfo/python-list
