Can you show the whole statement? Most likely, this was embedded in some other call, e.g.: foo(*self.method()) If this is the case, the * does not bind to "self"; it binds to all of (self.method()), i.e.: foo(*(self.method())) This is just the foo(*args) syntax that unpacks a tuple into individual arguments to pass to foo(). http://docs.python.org/tutorial/controlflow.html#unpacking-argument-lists -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
