So just go ahead and import it wherever you need

If Kris' function is called lots of times, issuing an "import pygame"
in it will consume unnecessary cpu-power. This is because as soon as
soon as the function exits, the pygame-module will be unloaded.
Imported modules within functions will not be visible outside it,
because of the scope rules in Python.

dir()

['__builtins__', '__doc__', '__name__']

def foo():

...   import math
...   pass
...

foo()
dir()

['__builtins__', '__doc__', '__name__', 'foo']

def bar():

...   import string
...   print dir()
...

bar()

['string']

dir()

['__builtins__', '__doc__', '__name__', 'bar', 'foo']

import math
dir()

['__builtins__', '__doc__', '__name__', 'bar', 'foo', 'math']
