Éric Araujo added the comment:

readlines might be discouraged; readline has its use cases (two days ago I used it to get one line to pass to csv.Sniffer.sniff), but next(file) works too, so it could be de-emphasized.  There may be a difference with respect to the trailing newline however; I don’t remember if __iter__ or readline keep it or not.
