No, this is normal for Python -- you must import a module to use it (not 
just its package).  Pygame actually does a trick with its sub-modules, 
which is probably what's causing the confusion.  For example, you can do

   import pygame
   pygame.display.something(...)

This works because in pygame/__init__.py is something along the lines of:

   import pygame.display

which brings "display" into the module namespace.  Most packages I know 
of don't do this trick -- you must import the packages you want explicitly.

Cheers
