Working with paths

Hello, I finally had a look at the pathlib module. (Should have done it long ago, but anyway...). Having in mind the replies from my older thread (File system path annotations), what is the best way to support all possible path types? def doit(path: str | bytes | os.PathLike): match path: case st

Best practices for using super()

As a follow-up to my yesterday's question - are there any recommendations on the usage of super()? It's clear that super() can be used to invoke parent's: - instance methods - static methods - constants ("static" attributes in the parent class, e.g. super().NUMBER). This all works, but are the

Multiple inheritance and a broken super() chain

Hello. The legacy code I'm working with uses a classic diamond inheritance. Let me call the classes *Top*, *Left*, *Right*, and *Bottom*. This is a trivial textbook example. The classes were written in the pre-super() era, so all of them initialized their parents and Bottom initialized both Left a

File system path annotations

Hello, what is the preferred way of annotating file system paths? This StackOverflow answer (and a few others) recommend using the str | os.PathLike union. However, byte arrays can be used as paths too, and including them would make the annotation
