Now wrap it up by adding in __imul__, which does in-place multiplication. Be sure to update self.value!

Anyone to assist?

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 __mul__(self, other):
        if "." in self.value:
            return float(self) * other
        return int(self) * other

    def __imul__(self, other):
        self.value = self * other
        return self.value

It looks like you're on task 2, but the instructions for task 1 included "Go ahead and add __rmul__, too." and it seems to be missing.

Did you accidentally remove it when you added __imul__?
