What exactly am I doing wrong here?

I am completely lost on the second part. Please help.

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, other):
        return self * other

    def imul(self, other):
        self.value = self + value
        return self.value

  1. I looked at the challenge and rmul() is missing from the code you've included in the question.

  2. But you said you are having problems with the second part, so I think if you fix the indentation on imul() it will work.

One issue with your code is that you're missing the underscores. Your code shows: def imul(self, other):

When it should look like this:

def __imul__(self, other):

Also, it should show self * other, not self + other, like this:

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