How to Use This Repo

As a Self-Learner

1. Start with Lec1-Data Types.py and work through each file in order
2. Read the code and comments in each file
3. Type out the code yourself rather than copying and pasting
4. Modify examples and experiment with changes to deepen your understanding
5. Complete the practice files (Lec5 Prac.py, Lec7-Prac.py) before moving on
6. Attempt the projects after finishing all learning modules

As an Educator

• Use the Learning/ directory as a lesson-by-lesson curriculum
• Assign the Projects/ directory as homework or take-home exercises
• Use the FreeCodeCamp solutions as reference implementations for teaching

Practice Problems

After each learning module, reinforce your skills with these external platforms:

• HackerRank Python - Track your progress in Hackerrank Basic Problems.py
• LeetCode - Filter by "Easy" and Python tag
• FreeCodeCamp Python v9 - Solutions included in this repo
