2,458 PointsCan't get equal result on __eq__ video within Basic Object-Oriented Python
Could someone check my code below to see why i'm not getting equal when comparing car_one and car_two?
class Car:
# Class Attributes
wheels = 4
doors = 2
engine = True
# The Initializer
def __init__(self, model, year, make='Ford', gas=100):
# Instance Attributes
self.make = make
self.model = model
self.year = year
self.gas = gas
# instance attributes don't have
# to be passed in
self.is_moving = False
def __str__(self):
return f'{self.make} {self.model} {self.year}'
def use_gas(self):
self.gas -= 50
if self.gas <= 0:
return False
return True
def stop(self):
if self.is_moving:
print('The car has stopped.')
self.is_moving = False
else:
print('The car has already stopped.')
def go(self, speed):
if self.use_gas():
if not self.is_moving:
print('The car starts moving.')
self.is_moving = True
print(f'The car is going {speed}.')
else:
print("You've run out of gas!")
self.stop()
class Dealership:
def __init__(self):
self.cars = []
def __iter__(self):
yield from self.cars
def __eq__(self,other):
return self.make == other.make and self.model == other.model
def add_car(self, car):
self.cars.append(car)
car_one = Car("Ka", 2020)
car_two = Car("Ka", 2020)
car_three = Car("Fiesta", 2000)
if car_one == car_two:
print('equal')
else:
print('not equal')
#my_dealership = Dealership()
#my_dealership.add_car(car_one)
#my_dealership.add_car(car_two)
#my_dealership.add_car(car_three)
#for car in my_dealership:
# print(car)

Check the location of your eq function. At the moment, it is sitting outside of your Car class. I've just tested the code with it in the correct place and it works fine. :)
Hope that helps.
