Ich habe gerade dieses merkwürdige Verhalten von Python 3.5 festgestellt:


Python 3.5.1+ (default, Mar 30 2016, 22:46:26)
[GCC 5.3.1 20160330] on linux
Type "help", "copyright", "credits" or "license" for more information.
 >>> import re
 >>> s = 'One\u2003Two'


 >>> re.search('\s+', s)
<_sre.SRE_Match object; span=(3, 4), match='\u2003'>
 >>> re.search('\s+', s, re.ASCII)
 >>>
     ^^^ # --> No match

 >>> re.split('\s+', s)
['One', 'Two']
 >>> re.split('\s+', s, re.ASCII)
['One', 'Two']

Bug?


Zum Verständnis: '\u2003' == em space, also ein Whitespace-Char in Unicode.
