What does the keyword 'global' really mean

[John Dean]

Hi
I have been looking through some Python code and I came across the keyword
'global'. I have looked through the docs and two or three Python programming
books for a full explanation of what 'global' really means. Would I be
correct in assuming that any variable prefixed with the keyword global would
allow that variable to be accessible across translation units, in other
words global is equivalent to the 'C' keyword 'extern' ?

Also, does Python have the equivalent of the 'C' keyword 'static'?
