Double quotes or single quotes -- doesn't matter. > It looks very complicated to me.

But if you insist, the page you are looking at is more of a cheat sheet . Try the python docs, and tutorial first.

I'm not good at regexes but it looks like it wants two open parens followed by any number of characters that are anything but a close paren, followed by two close parens. So whenever it finds that pattern it splits off what is on either side of it. > ...which produces: > > > ["This is a ", "((test))", " of the ", "((emergency broadcasting station.))" ] > -- > https://mail.python.org/mailman/listinfo/python-list -- Joel Goldstick http://joelgoldstick.com -- https://mail.python.org/mailman/listinfo/python-list
