I write a lot of typescript and rust. In those languages, when I want to understand some code I haven’t seen before, I always start by reading the types. Understanding what and how the data moves through a system is usually key to understanding everything. And usually I lean heavily on my editor for this - in typescript there’s a lot of value in the simple act of hovering over values to see what type they are.
I’m working with a medium size python program at the moment. It’s mostly written by someone smart but early career, and they’ve made a rabbit warren of classes and mixins that get combined in complex ways. I’ve been encouraging him to add types - and wherever those types exist, the code becomes 100% more legible to my code editor - and ultimately to me.
I don’t think I’d bother with types in Python for small programs. But my experience is that good type hints lay out a welcome mat to anyone who comes along later to figure the code out. And honestly, a lot of the time that person is the original author, just months or years after the code was written.
