Well, you could do it with a class. But if I'm understanding correctly, maybe it's simpler than that: >>> def inject(*args, **kw): ... def wrapper(func): ... def go(): ... return func(*args, **kw) ... return go ... return wrapper ... >>> @inject(20, 22) ... def add(a, b): ... return a + b ... >>> add() 42 -- http://mail.python.org/mailman/listinfo/python-list
