except ZeroDivisionError:
ave = 0
return ave
You don't use value_list here you use self.value. So you don't need

No, this has nothing to do with objects, its just a broken algorithm.

I made a few changes, but I'm getting the same error on variance (see below):
Looks like a different error to me!
It would seem to me that it should never evaluate if the denominator is zero
because of the if
