13,579 PointsI need to you add __mul__ to NumString so we can multiply our number string by a number. Go ahead and add __rmul__, too.
Need help tell me what I am doing wrong. Thanks.
class NumString:
def __init__(self, value):
self.value = str(value)
def __str__(self):
return self.value
def __int__(self):
return int(self.value)
def __float__(self):
return float(self.value)
def __add__(self, other):
if '.' in self.value:
return float(self) + other
return int(self) + other
def __radd__(self, other):
return self + other
def __iadd__(self, other):
self.value = self + other
return self.value
def __mul__(self, other):
self.value = self * other
return self.value
def __rmul__(self, other):
return self * other

Your rmul is correct.
Have a look at the__mul__ and compare to how the__add__ is implemented. You need to check you see you you're working with an Integer or a Float. If you follow the structure of the __add__ method, I'm sure you'll get it.
Nice work! :)

1,511 PointsWhy do we need to add : if '.' in self.value:
to mul but not to rmul?
