You mean : "what's the usual way to define a function taking multiple *mandatory* arguments" ? I'd think it's explained in your book ??? def f(a, b, c): print a, b, c But this is such a cs101 point that we're surely misunderstanding each other here. > > > or (slightly more involved, and certainly overkill): > > > def with_default_args(default): > > def decorator(func): > > def wrapper(*args): > > if not args: > > args = default > > return func(*args) > > return wrapper > > return decorator > > > @with_default_args((0,)) > > def f(*a): > > print a[0] > > Now, this is interesting. Thanks! :) Dont take this as a "recommanded" solution to your problem - it was (mostly) to be exhaustive (and a bit on the "showing off" side too to be honest). -- http://mail.python.org/mailman/listinfo/python-list
