You should add a global statement or else python thinks a variable used
is a local:
def mud():
global dept
dept+=1
print dept

Ok. Thanks for the answers. :) I was a bit puzzled of
the fact that I could read but not assign to a global variable.
If you assign before a read, you create a local variable.
If you read only, you get a global access.
If you do a read before an assignment, you get an error message.
