Very cool use of string.join('()'). It does remind of a female body part, though. Naughty Veky. :)))

It seems you're suffering from a certain deficit. :-P `blah.join('lr')` is an ordinary way to enclose blah in parentheses. And `()` is, well, just an empty tuple. It also features every time you call a function without arguments. I'd say it happens too often to associate strongly of anything.
