我有一份日期清单。一些日期使用from dateutil import parser
进行解析,但其他日期不会。未解析的日期列表如下: -
date1 = 'Tue Feb 10 2015 12 52pm IST'
date2 = '10 February 15 08 35am'
date3 = '2015 02 10 08 24 26 UTC'
我按以下方式解析日期: -
try:
date = re.sub('[^a-zA-Z0-9\n\.]', ' ', date)
print date
print (parser.parse(date)).date()
except Exception,e:
print e
如何解析所有日期格式?这些是从网页上删除的日期。
最终输出的格式应为"Monday, 09 Feb"

不要删除这么多信息。留在:
冒号(你的正则表达式删除它们,但我打赌在你破坏它们之前有那里);如果有时间分隔符,您的日期就会解析:
>>> from dateutil.parser import parse
>>> date1 = 'Tue Feb 10 2015 12 52pm IST'
>>> parse(date1)
Traceback (most recent call last):
