I used to belong to the cult "don't repeat yourself" in the comments, being angry against people who thought I couldn't understand by myself the simplest line of code.
But I changed my mind. I've read some code comments over the years and best ones (imo) where those which where actually repeating themselves.
Golden rules of comments:
# state what you plan to do
cells = ['a', 'b' 'c']
# print the first cell
A bug that is easily spotted thanks to the comment. It's all about implementation versus intentions. Also note that comment should be written for the future self, and most importantly, for the current others.
