I think part of the problem is that you're looking at KEYDOWN events. Those
only happen when a key is pressed, meaning there's only one no matter how
long you hold the key. So the code would make your character move for one
frame, then stop.

You could make the character move every frame (eg. setting a speed and
moving by that speed per frame) until a KEYUP event happens. A different
way to handle things is to use pygame.key.get_pressed() (see
http://www.pygame.org/docs/ref/key.html ), which tells you what keys are
down at the moment you ask. You then say, "keys_down =
pygame.key.get_pressed" then "if keys_down[K_RIGHT] ## move right", and so
on.

One example is in my messy code at
http://kschnee.xepher.net/code/squirrelgame/squirrel4.py.txt , under
"Controls".
