STEP 1

Different cats - different names

__init__ starts when an object is created. It receives name and stores it in self.name.

class Cat:
    def __init__(self, name):
        self.name = name

✦ self means this cat.

STEP 2

Now the name must be written in brackets Cat(). The object will remember its version.

pet = Cat("Мур")
print(pet.name)

✦ For the class, «Мур» will appear from the first step.

IN-CLASS PRACTICE

Dial class and object. Check the two indentation levels.

class Dog:
    def __init__(self, name):
        self.name = name
pet = Dog("Рекс")
print(pet.name)

HOMEWORK

Create Cat with __init__(self, name), which saves name to self.name. Create a pet with the name «Мур» and output its name.
