By spending thirty seconds googling:

If your needs are very simple, something as simple as this will do it:

def memoize(func):
    def f(arg, _cache={}):
        if _cache.has_key(arg):
            return _cache[arg]
        t = func(arg)
        _cache[arg] = t
        return t
    return f

I don't even know what that means. Would you like to translate?
