2. Structuring Your Project

Organizing code properly makes it maintainable and scalable.

Recommended Project Structure

project_name/
│── app.py          # Main application file
│── requirements.txt # List of dependencies
│── README.md       # Project documentation
│── .gitignore      # Ignore unnecessary files
│── src/            # Source code folder
│   ├── modules/    # Custom modules
│   ├── static/     # Static files (CSS, JS, images)
│   ├── templates/  # HTML templates (if applicable)
│   └── database/   # Database files
└── tests/          # Unit tests

3. Version Control with Git & GitHub

Using Git helps track changes and collaborate with others.

Initialize a Git Repository

git init
git add .
git commit -m "Initial commit"

Push to GitHub

git remote add origin https://github.com/yourusername/project_name.git
git push -u origin main

Best Practices for Git

• Write meaningful commit messages.
• Use branches for new features (git checkout -b feature-name).
• Submit pull requests when contributing to projects.

4. Contributing to Open Source

Open-source contributions help improve your skills and build your reputation in the developer community.

How to Contribute to Open Source

1. Find a project – Browse GitHub repositories with the good first issue label.
2. Fork the repository – Create your own copy.
3. Clone the repo – Download it to your machine.

   git clone https://github.com/yourusername/project_name.git
   

4. Make changes – Fix bugs, improve documentation, or add features.
5. Commit and push – Submit a pull request for review.
