On the other hand, the Chimp tutorial itself uses 'is' in a lot of its
comparisons.  For example, its main loop does:

###
    if event.type is QUIT:
        return
    elif event.type is KEYDOWN and event.key is K_ESCAPE:
        return
###

There's not a single '==' mentioned in the Chimp tutorial.  I know 'is' is
done for efficiency's sake, when testing for identity is equivalent to
equality... yikes, that sentence came out awkwardly.  *grin*

But for the Pygame tutorial, perhaps it might be better to use '=='
instead?
