class xrange(object):
    def __init__(self, x):
        self.offset = 0
        self.x = x
    def __len__(self):
        return self.x
    def __iter__(self):
        return self
    def next(self):
        if self.offset == self.x:
            raise StopIteration
        retval = self.offset
        self.offset += 1
        return retval
