Implementation

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.

Note

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

Task

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

Task

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