I would expect the latter.

However, why global?
What's the use case for having global variables in the first place?
If I want to alter a variable that is not in the current scope, I use a
class:

class Foo:
    x = 0
    def f(self):
        self.x = 3

According to Google codesearch, it is hardly used in the Python library:

Is global evil?

Just asking.
