https://docs.python.org/2/library/re.html#regular-expression-syntax Section 7.2.1. Regular Expression Syntax Documentation for \w and \W are wrong. To be specific: \w is to match any non-alphanumeric character, while \W is to match alphanumeric character Fix: swap documentation for \w and \W |

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. |
