Initialize repository scaffolding for Jupyter notebook learning modules

[Copilot]

Set up clean project structure for Jupyter notebook-based practice materials and learning modules.

Changes

• .gitignore: Replaced AL/Business Central config with Python/Jupyter patterns

  • Excludes .env, .ipynb_checkpoints, __pycache__, virtual environments
  • Standard Python distribution, testing, and IDE artifacts

• README.md: Documentation covering repository purpose, structure, and environment setup

  • Prerequisites and installation steps (Python 3.8+, venv, Jupyter)
  • Proposed module organization structure
  • Contributing guidelines and best practices

• .env.example: Environment variable template with OPENAI_API_KEY placeholder

Setup Example

python3 -m venv env
source env/bin/activate
pip install jupyter notebook
cp .env.example .env
jupyter notebook

No sample code included—foundation only.

Original prompt

Set up this repo for Jupyter notebooks used as practice materials for different learning modules. Create a professional README.md explaining purpose, structure, and environment setup. Add a Python/Jupyter-optimized .gitignore (exclude .env, .ipynb_checkpoints, pycache, env folders). Include a .env.example with OPENAI_API_KEY=. Do not add sample code — only clean project scaffolding.
