⚙️ Setup & Usage

Requirements: Python 3.10+

# Clone the repository
git clone https://github.com/am-robin11/Python-Programming-Fundamentals.git
cd Python-Programming-Fundamentals
 
# Run any file directly
python 01_Fundamentals/01_variables_and_datatypes.py

No external dependencies are required for most files. Any file that needs third-party libraries will mention it in a comment at the top.
