Question

I\'ve been trying to learn Python, and while I\'m enthusiastic about using closures in Python, I\'ve been having trouble getting some code to work properly:

I think the best way would be:

class Memoized(object):
    def __init__(self,func):
        self.cache = {}
        self.func = func
    def __call__(self,*args):
        if args in self.cache: return cache[args]
        else:
            self.cache[args] = self.func(*args)
            return self.cache[args]
