You may have begun your Python journey interactively, exploring ideas within Jupyter Notebooks or through the Python REPL. While that’s great for quick experimentation and immediate feedback, you’ll likely find yourself saving code into .py files. However, as your codebase grows, knowing where things should go in your script becomes increasingly important. Transitioning from interactive environments to structured scripts helps promote readability, enabling better collaboration and more robust development practices. This video course shows you the foundations of organizing a Python script: where the runnable bits go, how to arrange your imports, and how to refactor with constants and a fixed entry point. This is a portion of the complete course, which you can find here: https://realpython.com/courses/structuring-your-python-script/ The rest of the course covers: - Formatting With Ruff - Using Constants - Fixing Formatting Briefly - Creating a Fixed Entry Point - Exercise: Structure a Script With a Name-Main Guard - Structuring Your Python Script (Quiz) 🐍 Become a Python expert with real-world tutorials, on-demand courses, interactive quizzes, and 24/7 access to a community of experts at https://realpython.com ▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰ 🐍 Start Here → https://realpython.com/start 🗺️ Guided Learning Paths → https://realpython.com/learning-paths 🎧 Real Python Podcast → https://realpython.com/podcast 📚 Python Books → https://realpython.com/books 📖 Python Reference → https://realpython.com/ref 🧑‍💻 Quizzes & Exercises → https://realpython.com/quizzes 🎓 Live Courses: https://realpyth
