Magic Methods, R Methods

Question

I now understand the concept of Magic Methods. On a slide, it says as an example, x + y is translated into x.__add__(y). However, if x hasn't implemented __add__, and x and y are of different types, then y.__radd__(x) is called. It also says there are r methods for all magic methods mentioned, such as _sub_, _or_, _xor_ etc. But as I read on, I see comparison methods like _lt_ and _contains_ for in. Do r methods apply to them as well?

Hi
I think your question is quite intriguing, and actually I found a rather comprehensive explanation of magic methods
https://rszalski.github.io/magicmethods/
However, found no proof of what you actually asked :)
That would be a fun OOP project to test this hypothesis with two different custom classes and customised comparison operators.
If you found the answer in the meantime, I would be very interested to hear!
