Question

Hi could you explain why my code is not working for b = a + a + a (it's a review question)

Answer 1

__add__ method must return a new Dist Object to make it work

OUTPUT:

CODE :

class Dist:
def __init__(self,miles=0.0):
self.m = miles

def __repr__(self):
result = round(self.m,1)
return str(result)+'miles'

def addKilo(self):
self.m+=0.62

def __add__(self,other):
total = self.m + other.m
return Dist(total)
