 As a last note on sets, you can also define a set as any character *but* those in the set. You do that by including the character ``"^"`` as the *very first character in the set*. Thus, ``[^a]`` would match any character excluding "a". That's called complementing the set. Those escape sequence shorthands we saw earlier can also be complemented: ``"\D"`` means any non-number character, thus being equivalent to ``[^0-9]``. The other shorthands can be complemented by, you guessed it, using the respective uppercase letter instead of the lowercase one. So, going back to the example ``<p[^>]*>`` from the previous section, now you can see that the character set it's using tries to match any character except for a closing angle bracket.
