Structuring Python Code with Modules and Packages

As your Python projects grow, keeping all your code in a single file becomes unmanageable. Learning how to structure your code into logical, reusable components is the key to writing clean, maintainable software. This text-based course guides you through the core concepts of Python modules and packages. You will transition from writing single-script programs to designing modular codebases that are easy to read, test, and share with others. What you'll learn: First, understand the fundamental differences between Python modules, packages, and libraries. Second, import code efficiently using absolute and relative import paths. Third, create and structure your own custom packages with initialization files. Fourth, manage project dependencies safely using modern virtual environments. Fifth, package and prepare your Python code for distribution and reuse. Sixth, apply best practices for code organization and namespace management. You will start by mastering foundational terminology and basic import mechanisms. From there, you will progress to building multi-file packages and exploring modern dependency management workflows. This course is designed for beginner Python programmers who want to improve their code organization, with no prior experience required.
