> Especially when there are linter rules requiring comments you'll have something like def open_thing(x, y): and a comment, "defines a function that opens thing."

I actually think those comments are useful in two ways:

1. The process of writing a comment will help often help me rename the function/variables so e.g. “defines a function that opens thing” becomes something like “opens can_of_worms with the given instrument and restraints” for the method definition open_can_of_worms(instrument, restraints)

2. You can use variable/return value comments to further restrict the domain of values, e.g. non-null, positive or in the range 1-42 (arguably it would be better to express some of these in the type system, but that is a different discussion). These comments show up in my IDE when I try to call the code in a remote location, so I don’t have to guess or remember the constraints.
