跟老师的代码一摸一样，为什么报错，那位大佬帮个忙

我是小白，最近在学类，为什么一有类变量就报错呢，向大佬请教！
代码如下
class Car:
def int(self, model, year):
self.model = model
self.year = year

def drive(self):
    print("i can drive!")

my_car = Car(‘bmw’, ‘2022’)
print(my_car.model, my_car.year)
my_car.drive()

报错提示：Traceback (most recent call last):
File “C:\Users\Administrator\PycharmProjects\pythonProject\uygtftu.py”, line 11, in
print(my_car.model, my_car.year)
^^^^^^^^^^^^
AttributeError: ‘Car’ object has no attribute ‘model’
