Yes, I invented that, and you could have found it more easily in the Python
FAQ (note that the inner parens aren't needed -- "and" binds tighter than
"or").  However, I have never used it in real code, and have been known to
kill people who do.  You really want to risk that, just to avoid an obvious
if/else <wink>?
