Python Packaging Explained: setup.py vs pyproject.toml (2026 Guide)
Are you still using setup.py to package your Python code? It's time to upgrade! 🚀 In this video, we break down the modern standards for distributing Python applications professionally in 2026.
We explore why packaging matters, the security risks of the legacy setup.py method, and why the community has moved to the declarative pyproject.toml standard (PEP 517/518). You will learn how to structure your project metadata, manage dependencies without requirements.txt, build wheel artifacts, and publish your library to the Python Package Index (PyPI).
Whether you are a beginner looking to share your first script or an experienced developer updating your workflow, this guide covers everything you need to know to follow best practices. 📦✨
