For consistency, we should probably have "whitespace" for re equal to whatever "\s" matches, since this is what the engine itself considers as whitespace (and then also covers the special case where you use the re.ASCII flag).
Still, the only practical case I could imagine, where extending the list would indeed make sense, is to have the character qualify as whitespace for re.VERBOSE, since this can sometimes be introduced via copy&paste from other sources (e.g. web pages showing a regular expression). Due to whitespace being what it is, it's hard to tell whether you've just copied a \u0020 or a \u00a0. The latter can easily render the regular expression non-working with the current interpretation of re.VERBOSE. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Nov 20 2017) >>> Python Projects, Coaching and Consulting ... http://www.egenix.com/ >>> Python Database Interfaces ... http://products.egenix.com/ >>> Plone/Zope Database Interfaces ... http://zope.egenix.com/ ________________________________________________________________________ ::: We implement business ideas - efficiently in both time and costs ::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
