multiplication

what could be the answer to this question please I need to you add mul to NumString so we can multiply our number string by a number. Go ahead and add rmul, too.

numstring.py
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 __rmul__(self,number,other):
        self.number =number
        return int(self.number) * other

You've added "__rmul__" but you still need "__mul__".

And the "__add__" and "__radd__" methods already provided make great models to refer to when creating both of the new methods.
