multiplying a number string with another number
So as the question asks , I tried to multiply the number string with another number , but code still not passing
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 = str(value) * other return self.value def __rmul__(self, other): return self.value

Since you want to do math, you won't be converting anything to a string ("
str()"). You'll want to go the other way. And you won't need to directly reference "self.value" for the first task.
The challenge has given you a great model to follow in the form of "
__add__" and "
__radd__". The functions you need to make will be almost identical except for a different math operator to multiply instead of add.
