usage of self.value versus self why are we using self inside add, radd methods instead self.value
why are we using self instead of self.value in add, radd, etc. how is self inside the radd working with out casting it to Int
why is my code failing when i write like this
def __add__(self, other): return int(self) + other ''' why cant we write like this what is the difference between self and self.value in this context ''' #return int(self.value) + other def __radd__(self, other): return self + other ''' why cant we write like this ''' #return int(self.value) + other

You don't need to access the "value" property because the built-in conversion processes do it for you when you perform an operation directly on a class instance.
And you don't want to use explicit "int" conversion, since the values might be floating point, and the built-in conversions will take care of that if you allow them to do their job.

int(self) only works when you have def int(self): return int(self.value)
If not then only int(self.value) would work
