Module 5: Classes and objects

Module Description

This module focuses on object-oriented programming in Python, covering attributes, methods, operator overloading, and class-level versus instance-level attributes.

Assignment 1: Homework on "Attributes and Methods of an Object"

  • Solution
  • Description: Task "Developer - Not Just a Coder":
    • Implement a House class with attributes for the name and number of floors. The class should include a method go_to that prints the floor numbers from 1 to the specified floor or an error message if the floor doesn't exist.

Assignment 2: Homework on "Special Methods of Classes"

  • Solution
  • Description: Task "Magical Buildings":
    • Extend the House class to include special methods like __len__, which returns the number of floors, and __str__, which provides a formatted string representation of the house.

Assignment 3: Homework on "Operator Overloading"

  • Solution
  • Description: Task "Operator Overloading":
    • Implement comparison operators (__eq__, __lt__, __le__, etc.) for the House class to compare buildings by their number of floors. Also, implement the __add__, __radd__, and __iadd__ methods to increase the number of floors.

Assignment 4: Homework on "Class Attributes vs Instance Attributes"

  • Solution
  • Description: Task "Construction History":
    • Add a class-level attribute houses_history to track all created house objects. Implement the __new__ and __del__ methods to automatically record new houses and log when a house is demolished.

Additional Assignment: Practical Exercise on "Classes and Objects"

  • Solution
  • Description: Task "UrTube Platform":
    • Implement a set of classes (User, Video, UrTube) to simulate the behavior of a video-sharing platform, including user registration, video uploading, and video watching with age restrictions and playback tracking.
