我正在尝试使用 python 编写一个 REGEX 来根据(英国:日-月-年)识别日期。
我写了一些随机字符串,如下所示。
string='these are just rubbish 01-13- 00-00- 44-44- 11-2-2222 24-3-1695abc 12-13-1111 32/11/2000\
these are actual dates -- 4-02-2011 12/12/1990 31-11-1690 11 July 1990 7 Oct 2012\
these are actual deal-- by 12 December six people died and by 18 Nov 19902.00 dollar was spent\
anomalies -- are he gave June 2000 bucks in 5 July. The shares rose 5% on 5 November 1999.'
re.findall('(\
([1-9]|0[1-9]|[12][0-9]|3[01])\
[-/\s+]\
(1[1-2]|0[1-9]|[1-9]|Jan|January|Feb|February|Mar|March|Apr|April|May|Jun|June|Jul|July|\
Aug|August|Sept|September|Oct|October|Nov|November|Dec|December)\
[-/\s+]\
(1[0-9]\d\d|20[0-2][0-5])\
[^\da-zA-Z])', string)
我得到的输出如下:
[('2/11/2000 ', '2', '11', '2000'),
('4-02-2011 ', '4', '02', '2011'),
('12/12/1990 ', '12', '12', '1990'),
('31-11-1690 ', '31', '11', '1690'),
('11 July 1990 ', '11', 'July', '1990'),
('7 Oct 2012 ', '7', 'Oct', '2012'),
('5 November 1999.', '5', 'November', '1999')]
正则表达式格式似乎有效,但是,正则表达式无法识别一些日期:
by **12 December** six people
by **18 Nov** 19902.00 dollar
我如何修改正则表达式,以便它也识别上述日期。
