In rmul why don't we have to turn the self.value into a float and integer like we did in mul?
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

39,021 PointsHey Andrew,
I very strongly recommend you go back and watch the video just before this challenge, because Kenneth explains this in detail for __add__
and __radd__
.
The same holds true for __mul__
and __rmul__
: you could write it all out, but you don't need to, because Python will ultimately just call the __mul__
method from the __rmul__
method.
Please go back and watch the video again, though, because Kenneth does a great job explaining it, starting at around 2:30 and ending around 4:30.
Cheers
-Greg
