Comments explain why, not what. Any comments that explain what a section of code is doing would probably be better off as separated methods.

Apart from basic documentation comments, like JavaDoc or C#'s XML documentation comments.

There's nothing limiting what a comment should be as far as I know.

As an example of what I mean, I've seen in a 10k+ lines python code a few lines of bit manipulation. There was a comment explaining what those lines did and why. They didn't expect everyone to be proficient in bit manipulation but it made it so that anyone could understand anyway.

Nothing technical, sure. Just good coding practices.
