Why isn't this working?

I don't understand why my NumString isn't working I believe I copied the code verbatim.

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

#r for reflected 
def __radd__(self, other): 
    return self + other

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