Oh -- sorry about that... :))


Function definition:

def f():
    i = i+1

Now, we define a global variable:

i = 1

If we now try to call f(), we will get an error, since i does not
exist in the local namespace of f. That's all. If we wanted f()
to work, we would have to write:

def f():
    global i
    i = i+1

Quite the opposite of Lua, I guess. :)
