I do not know what I have done wrong with the __imul__ method.

The question asked me to wrap it up by adding the imul method and do not forget to update self.value. Therefore, I did and it fails.

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 __rmul__(self, other):
        return self * other

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

You're just using the wrong variable name.

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

you want to multiply self * other. just a mistake from the monotonousness of this challenge i'm sure.

Oh, opps... I put "value" instead of "other"
