This is not "replacing a method in a class", but replacing it in an instance. > t.update(5) # this one doesn't work, gives > # TypeError: another_update() takes exactly 2 arguments (1 given) > > clearly it isn't seeing it as a method, just an attribute which happens > to be a function. Is there a preferred way to do this? import types t.update = types.MethodType(another_update) -- http://mail.python.org/mailman/listinfo/python-list
