Technically | is better but mimicking lists, + might sound better. It follows the general trend in Py. <<I don't think beginners should be taught these operators as a major tool in their toolbox>> True, fits more of a "Python Tricks" session but sometimes according to the audiance level it is tempting to just mention it since it's one line away. <<The natural way of discovering these would be through tutorials, ..., not by trying random key combinations in the REPL.>> *smile* >
