That's correct. > So can someone tell me why a triple-quoted string gives a syntax error > if only in one line? Because the string literal – it doesn't matter how it's quoted – can only appear where the syntax allows for a string literal. It isn't a comment, so it can't be freely substituted for a comment. > Can someone also provide a sort of a 'guide' to triple-quoted comments > in general? The guide is simple: There are no triple-quoted comments in Python. If you triple-quote a string literal, it is still a string literal and must follow all the syntax rules for string literals. -- \ “[The RIAA] have the patience to keep stomping.
