🚀 Getting Started

Prerequisites

• Python 3.10+ — Download here
  • ⚠️ During installation, make sure to check "Add Python to PATH"!

How to Use

1. Clone this repo:

   git clone https://github.com/subimpact/python-fundamentals.git
   cd python-fundamentals

2. Set up a Virtual Environment (venv) — Sangat Recommended! 🛡️ To avoid polluting your global system packages, create and activate a Python virtual environment:

   • Windows (PowerShell):

     python -m venv venv
     .\venv\Scripts\Activate.ps1

   • Windows (Command Prompt):

     python -m venv venv
     venv\Scripts\activate.bat

   • macOS / Linux:

     python3 -m venv venv
     source venv/bin/activate

3. Install Dependencies:

   pip install -r requirements.txt

4. Read and run lessons in order:

   python lessons/00_hello_python.py
   python lessons/01_variables_and_types.py
   # ... and so on

   (Need to verify if your console output matches what it should? Check EXPECTED_OUTPUTS.md!)

5. Try the exercises:

   # Open the exercise file, fill in the TODOs
   # Then run it. There are built-in Malaysian checkers to guide you!
   python exercises/01_variables_exercises.py
   
   # Check the solutions when you're done:
   python solutions/01_variables_solutions.py

Optional: Check your code style (PEP-8)

requirements.txt includes black and flake8 so you can learn good code standards from day one:

black --check lessons/    # Is your code formatted the standard way?
flake8 exercises/         # Any style or logic warnings?

You don't need to use them to finish the course — but learning them early makes your code look professional.

Recommended Workflow

1. 📖 Read the lesson file (it's heavily commented — just read it like a book!)
2. ▶️ Run the lesson and verify your output matches EXPECTED_OUTPUTS.md
3. 🧪 Try modifying the code to experiment
4. ✏️ Do the matching exercise and run it to trigger the automated checker
5. ✅ Check the solution
6. ➡️ Move to the next lesson

⏱️ Estimated Playthrough Duration

For absolute beginners, here is a realistic guide on how long it takes to finish this course:

• Per Topic (Lesson + Exercise + Solution): ~30 to 45 minutes
  • 15-20 mins: Read the lesson file, run it, and experiment.
  • 15-25 mins: Code the exercise, debug with the checker, and review the solution.
• Full Repository Playthrough: 6 to 8 hours of total hands-on learning.

📅 Recommended Learning Paths:

• The "Teh Tarik" Weekend Sprint ☕: Dedicate 3-4 hours on Saturday and Sunday. You'll be coding comfortably by Sunday night!
• The Self-Paced Mamak Plan 🍛: Do 2 topics a day (approx. 1 hour total). You'll finish everything in exactly one week, confirm steady!

🎯 Who Is This For?

• Absolute beginners who have never coded before
• Students starting a CS or data science course
• Developers from other languages picking up Python
• Anyone who wants a fun, easy-to-follow Python refresher
