How????are!!!you
I’d like to split the string into ['How','are','you'].
I’ve tried the following regex:
\?*|\!*
which does not work. However, the following regex works:
\?+|\!+
Anyone explain this to me?
As for why
\?*|\!*doesn’t work, just look at whatre.findallfinds:The alternation always takes the first branch if possible.
re.splittries to only split by nonempty matches, so you end up splitting by?but not!(since\?*will match any empty string,\!*will never match in a non-overlapping fashion).
