Use it as a tutorial, a refresher, or a reference it's just intended to be a user-friendly guide to Python's magic methods. I started out with weekly blog posts, and now that I've finished with those, I've put together this guide. So, to fix what I perceived as a flaw in Python's documentation, I set out to provide some more plain-English, example-driven documentation for Python's magic methods. There's hardly an example to be found in that section (and that may very well be by design, since they're all detailed in the language reference, along with boring syntax descriptions, etc.). All of the magic methods for Python appear in the same section in the Python docs, but they're scattered about and only loosely organized. They're also not as well documented as they need to be. They're always surrounded by double underscores (e.g. They're special methods that you can define to add "magic" to your classes. What are magic methods? They're everything in object-oriented Python. This guide is the culmination of a few months' worth of blog posts. Making Operators Work on Custom Classes.
There, along with comments, (or even contributions!). The magic methods guide has a git repository at.
