And makes the star solution half unuseful. >>> def f(*args,**kwargs): ... pass ... >>> f(*(1,2,3),iter=True) File "<stdin>", line 1 f(*(1,2,3),iter=True) Leaving out what I just asserted in the previous thread :( I suppose you meant output((x*x for x in range(10)), iter=1) f(1,[2,3],(_ for _ in (4,5)),iter=True) Regards Paolino
