str.format problem

Tue, 22 Dec 2009 08:59:40 -0700

I have made a function that will output '{0}' when 0 is given and '{1}' for everything else.

class offset(str):
    def __init__(self,x):
        self.x=x
    def __repr__(self):
        return repr(str({int(bool(self.x))}))
    
    def end(self,end_of_loop):
    #Ignore this def it works how I want it to.
        if self.x==end_of_loop:
            return '{2}'
        else:
            return self

What I would like to do is offset(1).format('first', 'next') but that only outputs '1' for some reason. What can I do?
