Python Modules and Packages: Organizing and Distributing Code

Writing all your Python code in a single file quickly becomes unmanageable as your projects grow. Understanding how to structure your code into modules and packages is the key to writing clean, maintainable, and professional software. This text-only course guides you from Python basics to structured code organization. You will learn how to break down complex programs into reusable components, manage dependencies safely, and prepare your code for distribution. What you'll learn: - Master the fundamentals of Python modules, imports, and namespaces - Design custom packages and manage complex import hierarchies - Configure virtual environments to isolate project dependencies safely - Apply modern packaging workflows using tools like Poetry or uv - Implement type hints and basic code styling to ensure high-quality modules - Prepare your packages for distribution and local installation You will start with foundational concepts of namespaces and simple imports, progress through nested package structures, and finish with modern dependency management and packaging practices. This course is perfect for beginner Python developers who want to transition from single-file scripts to structured, professional codebases. No prior packaging experience is required.
