Python Dekoratoren einfach erklärt | Python-Kurs #94

🐍 Python Community: https://tr.ee/python-skool ☕ Buy me a coffee: https://buymeacoffee.com/binaerverkehr Every time you write a Python class, you repeat the same code: _init__, __repr__, __eq_ – annoying boilerplate that needs to be maintained with every change. In this episode, I'll show you how decorators work and how you can get rid of this boilerplate once and for all. First, you'll learn why functions in Python are considered first-class citizens and what that means in practice. Building on that, we'll create our own function decorator step by step, and then a class decorator that automatically generates _init__, __repr__, and __eq_ – essentially a custom version of Python's built-in @dataclass. By the end, you'll not only know how to use decorators, but also how they work under the hood. First, you'll learn why functions are considered first-class citizens in Python and what that means in practice. ⏱️ Timestamps: 00:00 – The Boilerplate Problem 03:23 – Python Community 03:50 – Functions are Objects 06:14 – Decorating Functions 09:37 – Decorating Classes 15:36 – Using Your Own DataClass Decorator 16:52 – End 🔗 Links: 📖 Python Docs – Data Classes: https://docs.python.org/3/library/dat... 📖 Python Docs – Decorators: https://docs.python.org/3/glossary.ht... 🌎 Source Code (Community): https://www.skool.com/python-communit... #python #pythontutorial #pythondeutsch #dekoratoren #programmieren #dataclass
