However, you can dispatch back to the instance if you really must:
class MyObj(object):
def __init__(self):
self.__str__ = lambda self: "I'm an object!"
def __str__(self):
return self.__str__(self)
But honestly, this sounds like a bad idea. If instances of the one class
have such radically different methods that they need to be treated like
this, I question whether they actually belong in the same class.
