[Tutor] help on scope

[Charlie Clark]

Consider this:

count = 0

def func(something):
    print count
    count += 1

This will print 0 but generate an error about the assignment. I know this is 
a scope problem but my brain is having trouble with accepting the fact that 
although I can access a variable I can't reference it. Do I have to use 
global to get around this? How does global actually work?

def func(something):
    global count
    print count
    count += 1

Thanx for any help.
