Python Project Structure and Import Management

Have you ever encountered a frustrating ModuleNotFoundError when trying to run a Python script, or wondered why running a file works in one folder but fails in another? Managing imports and project layouts is one of the most common hurdles for Python developers. This course demystifies how Python locates files and helps you build clean, maintainable project structures. You will transition from blindly moving files around to designing robust Python packages that work seamlessly across different environments. You will learn the mechanics behind Python's search path, how to resolve relative import issues, and how to structure your code for distribution. What you'll learn: - Understand how Python searches for modules and packages behind the scenes. - Master the difference between executing scripts directly and using the module execution flag. - Design clean project layouts using standard absolute and relative import conventions. - Configure modern project metadata using pyproject.toml and virtual environments. - Resolve circular dependencies and common import path conflicts. This course begins with foundational concepts of Python's import system before moving into practical directory layouts and modern packaging workflows. You will read through clear explanations, analyze illustrative code layouts, and practice solving structural challenges. This course is designed for beginner to intermediate Python developers who want to stop fighting import errors and start organizing their code professionally. No advanced packaging experience is required. Learn how to structure your Python projects correctly and make import errors a thing of the past.
