You can access them without the global keyword - for "reading" .
You only need global if you are assigning to it - else you get a new function
local:
>>> x = 7
>>> def rubbish():
print x
>>> rubbish()
7
>>> def more_rubbish():
x = x+1
print x
>>> more_rubbish()
Traceback (most recent call last):
File "<pyshell#10>", line 1, in ?
more_rubbish()
File "<pyshell#9>", line 2, in more_rubbish
x = x+1
UnboundLocalError: local variable 'x' referenced before assignment
>>>def other_rubbish():
y = x+1
print y
>>> other_rubbish()
8
>>> x
7
>>> def global_rubbish():
global x
x = x + 1
print x
>>> global_rubbish()
8
>>> print x
8
