[docs] [issue27116] Documentation for regular expression alphanumeric matching are swapped. https://docs.python.org/2/library/re.html#regular-expression-syntax

[Xiang Zhang]

Xiang Zhang added the comment:

I don't think no need to swap. The current doc is right.

>>> re.findall(r'\W+', 'abcd123_#@@@@')
['#@@@@']
>>> re.findall(r'\w+', 'abcd123_#@@@@')
['abcd123_']

It's apparent that \w match alphanumeric and \W vice versa.
