Iterators are available in python 2.2
class enumerate:
    def __init__(self, inlist):
        self.inlist = inlist
        self.index = 0

    def next(self):
        if self.index >= len(self.inlist): raise StopIteration
        thisone = self.inlist[self.index]
        self.index += 1
        return self.index-1, thisone

    def __iter__(self):
        return self
