In this video, we answer that question by taking a small, messy script and refactoring it step by step using the core principles of idiomatic Python. Along the way, you’ll learn how to think like a Pythonista: using functions instead of unnecessary classes, leveraging dataclasses, writing readable control flow, embracing tools like pathlib and logging, and applying the Zen of Python in practice.
