I need help here.

This class should look familiar!

I need to you add mul to NumString so we can multiply our number string by a number. Go ahead and add rmul, too.

Important: In each task of this code challenge, the code you write should be added to the code from the previous task.
numstring.py class NumString: def init(self, value): self.value = str(value) ā€‹ def str(self): return self.value ā€‹ def int(self): return int(self.value) ā€‹ 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 __mu1__(self, other):
    if '.' in self.value:
        return float(self) * other
    return int(self) * other

def __rmu1__(self, other):
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 __mu1__(self, other):
        if '.' in self.value:
            return float(self) * other
        return int(self) * other

    def __rmu1__(self, other):
        return self * other

You just have a couple of spelling errors, which might be very hard to spot depending on your screen font.

You have "mu1" with a number one (1) at the end instead of "mul" with a lower-case letter "L" at the end.
The same issue is there with "rmu1" (one) instead of "rmul" ("L").
