Question

我在 python 中使用 datefinder 模块，我需要从字符串中提取 DateTime，但我从只包含一个日期和时间的字符串中获取多个日期。

代码：

hi
(61) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]

输入：

import datefinder
def date_using_datefinder(date_string):
    matches = datefinder.find_dates(date_string)
    for match in matches:
        print(match)

输出：

test3='''
[26/08/2018 06:58:29.126900]
[26/03/2004 06:58:29.126985][SDAP_CODEC][JET_AT_JUMP][43][HTXXHTXX] DUST_RPOP:QFI:9

'''

为什么会出现最后两个日期，我想这在字符串中没有任何地方。

PS：我也尝试过 DateUtil 模块，但它显示 ParseError。

仅供参考，代码为：

2018-08-26 06:58:29.126900
2004-03-26 06:58:29.126985
2003-02-06 06:58:29.254621
2022-05-20 06:58:29.124898
2020-08-26 06:58:29.136579
2045-08-02 00:00:00
2032-08-02 00:00:00

注意：在我的情况下使用正则表达式不起作用，因为我的日志行可以有随机模式和任何日期时间格式，或者我可以说不想使用正则表达式。

让我帮自己

我创建了一个 python 库来完成我的任务，如果需要其他人也可以使用这个库。试图涵盖大部分日期时间格式，并将更新更多。

是时候使用我们自己的库了

Installation -> pip install MyDateTimeLib==0.1.2
Importing as -> from MyDateTimeLib import myfunction
How to use? --> myfunction.date_find("passing date string")
Returns     --> it return the dictionary containing all the dates from the string else null dict.
check on    --> https://pypi.org/project/MyDateTimeLib/0.1.2/

演示：

data_for_date = '''
[26/08/2018 06:58:29.126900]
[26/03/2004 06:58:29.126985][SDAP_CODEC][JET_AT_JUMP][43][HTXXHTXX] DUST_RPOP:QFI:9
[02/06/2003 06:58:29.254621][SDAP_CODEC][JET_AT_JUMP][43][HTXXHTXX] DUST_RPOP:QFI:9[26/03/2036 06:58:29.126985]
[20/05/2022 06:58:29.124898][SDAP_CODEC][JET_AT_JUMP][43][HTXX] DUST_RPOP:QFI:9
[26/08/2020 06:58:29.136579][ALST][stx][29][ggg] JET_AT_JUMP:TRUX_MSGD_HTXX:13265261686865256:QWERT_DUMPING_TDD:45:DUST_RPOP_CVX:32:AXTP_DI:65576
'''

代码：

from MyDateTimeLib import myfunction
for x in data_for_date.splitlines():
    if len(x)>1:
        dic = myfunction.date_find(x)
        print()
        for k,v in dic.items():
            print(k,v)

输出：

Date:0 2018-08-26 06:58:29.126900

Date:0 2004-03-26 06:58:29.126985

Date:0 2003-02-06 06:58:29.254621
Date:1 2036-03-26 06:58:29.126985

Date:0 2022-05-20 06:58:29.124898

Date:0 2020-08-26 06:58:29.136579

为什么我从只包含单个日期和时间的字符串中获取多个日期？ Python
