I don't fully understand your objection to making a callable class, as that's probably how I'd do it. You were saying that it returned an object instead of the value... I just look at it as having a class that implements the functionality that you want and you create an instance of that class. >>> class fooClass: ... def __init__(self): ... self.n = 0 ... def __call__(self): ... self.n += 1 ... return(self.n) ... >>> foo = fooClass() >>> print foo(), foo() 1 2 However, another way to go about that is to set up a default argument which is a mutable object: >>> def foo(n = [0]): ... n[0] += 1 ... return(n[0]) ... >>> print foo(), foo() 1 2 I personally prefer the class mechamism because it's more obvious what's going on and less likely to produce misunderstsanding. You seem hell-bent on something more like the latter though. ;-) Sean -- Well, what does she expect?
