pop(1)?

Anyway if would be simpler and almost certainly faster to not bother 
checking before the pop:

def pop(self):
    try:
        return self.__heap.pop()
    except IndexError:
        raise InnerInterpreterError, "stack underflow"

and if performance mattered the OP might even consider pre-binding the pop 
method in __init__:

    self.__pop = self.__heap.pop

but that's probably premature optimisation.

Me too. It's a repost of something from 2004. Bizarre.
