Project Structure

Organizing a Python project is about more than just where files go—it's about creating a system that is navigable, extensible, and maintainable over time. As your project grows, a clear structure becomes essential not only for your own sanity, but also for enabling others to contribute effectively, whether they're teammates, students, or collaborators.

This section explores the principles and patterns behind effective project layout. You'll learn how to:

• Construct a scalable package hierarchy
• Choose between or combine layered and feature-based architectures
• Maintain clarity and separation between core logic, interfaces, and support utilities

A strong structure gives your code base a logical backbone. It makes it easier to:

• Isolate concerns between modules
• Test and reuse components independently
• Reduce duplication and accidental complexity
• Onboard new contributors quickly
