Are you sure?

    exarkun at charm:~$ cat foo.py
    colorIndex = 0
    
    def test():
        print colorIndex
    
    test()
    exarkun at charm:~$ python foo.py
    0
    exarkun at charm:~$                                           

The global keyword lets you rebind a variable from the module scope.  It
doesn't have much to do with accessing the current value of a variable.
