>>> class aud(object): ... def __init__(self, func): ... self.func = func ... @cacheit ... def __getitem__(self, arg): ... return self.func(arg) ... __call__ = __getitem__ ... >>> def ok(i): ... t=time() ... while time()-t<i:pass ... return i ... >>> o=aud(ok) >>> o[2] # takes 2 seconds 2 >>> o[2] # returns immediately 2 -- You received this message because you are subscribed to the Google Groups "sympy" group.
