Python OOP Practice Repository

Python Version

This repository was developed and tested using Python 3.11. It is recommended to use Python 3.10 or newer for best compatibility.

This repository contains a series of Python scripts and class files designed to help you learn and practice Object-Oriented Programming (OOP) concepts in Python. The exercises and code samples are organized sequentially, each building on the previous lessons to reinforce key OOP principles.

Contents

Core OOP Lessons (oop01.py - oop10.py)

Step-by-step OOP exercises and examples, covering:

• Classes and objects
• Attributes and methods
• Inheritance
• Encapsulation
• Polymorphism
• Special methods (dunder methods)
• Working with CSV files

Data Files

• oop07instances.csv: Sample data file used in one of the exercises for demonstrating file I/O with classes.

Multi-File Projects

oop11 Project:

• oop11_item_class.py, oop11_phone_class.py, oop11_main.py: Example of a small project structure with multiple classes and a main script, focusing on item and phone classes.

oop12 Project:

• oop12_item_class.py, oop12_phone_class.py, oop12_main.py: Further extension of the previous project, introducing more advanced OOP concepts.

oop13 Project:

• oop13_item_class.py, oop13_main.py: Additional practice with class design and usage.

oop14 Project:

• oop14_main.py: Standalone script for a specific OOP exercise.

oop15 Project:

• oop15_keyboard_class.py, oop15_main.py: Project files focusing on a keyboard class and its usage.

Additional Exercises

• oop16.py: Additional OOP exercise building on previous concepts.

Practice Problems

• practice01.py to practice05.py: Extra practice problems and challenges
  • practice01.py: Basic practice problem
  • practice02.py & practice02Upgraded.py: Practice with variations
  • practice03.py & practice04.py: Intermediate challenges
  • practice04again.py: Alternative implementation
  • practice05.py: Binary tree practice problem

Tutorial Source

The structure and exercises in this repository are inspired by the YouTube tutorial series:

Object Oriented Programming (OOP) in Python - Full Course by freeCodeCamp.org

or similar OOP Python tutorials available online. The code is organized to follow a progressive learning path, making it suitable for beginners and intermediate learners.

How to Use

1. Start with the earliest files (oop01.py) and progress sequentially.
2. Read the code, run the scripts, and experiment with modifications.
3. Use the CSV file and multi-file projects to understand real-world OOP applications.
4. Refer to the tutorial video or notes for additional explanations.
