Question

What is the output of this code?
class Animal:
i = 0
def _init._(self, name):
self.name = name
Animal.i += 1
class Cat(Animal):
i = Animal.i
def _init_(self, name):
self.name = name
Cat.i += 1
sylvester = Cat('Sylvester')
print(Cat.i)

Answer 1

1.

To understand what this code is doing, the Cat class has a class attribute called i. Everytime an object of type 'Cat' is initialized, i is incremented by 1.

So here you create one Cat object and print the value of i. I think you know what's going to happen.

HonFu looking at how this is a quiz question, I think he is wanting an explanation rather that posing a challenge to the community.

Answer 2

Please just run it in Code Playground and see for yourself.

Or ask us specifically what you don't understand.
