Not sure how "not liking something" equates getting things wrong, but I agree with most of what the author mentioned.

Using 'x' or 's' for a short lambda makes no difference. 's' could be anything, like 'x'. Unless you're specifically using django, there's no point in renaming _. Agreed with you on the argument lists and exceptions.

Python doesn't have NULL, I think you meant None.
