I don't think I understand the magic method concept. I have added the two methods as I visualise them. Am I completely off the mark?
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):
return self.value * int(other)
def __rmul__(self, other):
return int(other) * self.value

Take a look at how "__add__" and "__radd__" are handled in the existing code. What you need to do is very similar, but with different math operators.

Courses Plus Student 1,665 PointsThanks Steven, I think I just don't get the concept here

231,275 PointsWell, if you always call "int()" to do the conversion, it won't produce the correct result when the value has a decimal.
