Code

We start to fill the Cat class:

  • An attribute name with the predefined value 'Kitty';
  • A method say_meow().

We create an object cat and call the say_meow() method.


              
12345678910

            
class Cat:
  # An attribute
  name = 'Kitty'
  # A method
  def say_meow(self):
    print('Meow')

# Instantiating an object
cat = Cat()
cat.say_meow()
copy

Note

  • Each method obligatory contains self - a reference to the current object;
  • To call the method of the object, write Object.Method().
Oppgave

Swipe to start coding

  1. Add the sleep method.
  2. The sleep method prints a message.
  3. Instantiate an object using the cat variable.
