How to find the pygame example files?

[Piethon]

Hello.

Pygame has examples. On their website, stands this:

To get the files, run this code in the python interpreter:

>>> import pygame.examples.scaletest
>>> pygame.examples.scaletest.__file__
'/usr/lib/python2.6/site-packages/pygame/examples/scaletest.py'

I wanted to have the files for examples.aliens.
I've replaced the code above, by:

import pygame.examples.aliens
pygame.examples.aliens.__file__
'/usr/lib/python2.6/site-packages/pygame/examples/aliens.py'

Every time, I run it, nothing happens. It just says: Welcome to the pygame community: (Link to pygame website).
Nothing else happens.

So how can I find out, where those files are saved? Thanks for your help.
