No, you have Rect() available because you do this: from pygame.locals import * ammm, I thougt I imported Rect() with import pygame pygame.locals is just a convenience module to limit what gets added into ones namespace when doing a "from import *". The contents of pygame.locals is also found in the top level pygame package. -- Lenard Lindstrom

Re: [pygame] Rect() not imported
It's the pygame.locals line: >>> import pygame >>> pygame.Rect(0,0,5,6) >>> Rect(0,0,5,6) Traceback (most recent call last): File "", line 1, in Rect(0,0,5,6) NameError: name 'Rect' is not defined >>> from pygame.locals import * >>> pygame.Rect(0,0,5,6) >>> Rect(0,0,5,6) >>> Ian

Re: [pygame] Rect() not imported
If you import a module, it introduces the name of that module (pygame in this case) into the local scope. That means you can access things inside that module using that name (e.g. pygame.Rect). On the other hand, the from module import name construct imports the name itself. For example, if you said from pygame import Rect, then you could use Rect instead of pygame.Rect. Don't know if that's any clearer :) --Mike Gonzalo Castro wrote: Hello everybody! :) I'm reading some code from pygame's web and I found something that I don't really understand.
