python - 使用 datefinder 提取日期时间字符串

Question

matches = list(datefinder.find_dates(str(laslogsystime[0])))
if len(matches) > 0:
    date = matches[0]
    # print(date)

logging = re.findall(r'(.*?)', date)[0]
print(logging)

TypeError：预期的字符串或类似字节的对象

Answer 1

您必须尝试提取标识为日期时间字符串的字符串。datefinder

您不需要re.findall，您需要通过传递参数告诉find_dates返回包含日期时间和源字符串的元组：source=True

import datefinder
from datetime import datetime

laslogsystime = "August 1990 some text May 21 2015"
matches = [src for time, src in datefinder.find_dates(laslogsystime, source=True)]
print(matches) # => ['August 1990', 'May 21 2015']
