[英]Convert string to date using arrow python
I'm trying to convert string to date using arrow
module.我正在尝试使用
arrow
模块将字符串转换为日期。 During the conversion, I received this error: arrow.parser.ParserMatchError: Failed to match '%A %d %B %Y %I:%M:%S %p %Z' when parsing 'Wednesday 06 November 2019 03:05:42 PM CDT'
在转换过程中,我收到了这个错误:
arrow.parser.ParserMatchError: Failed to match '%A %d %B %Y %I:%M:%S %p %Z' when parsing 'Wednesday 06 November 2019 03:05:42 PM CDT'
The conversion is done using one simple line according to this documentation :根据本文档,使用一条简单的线即可完成转换:
date = arrow.get(date, '%A %d %B %Y %I:%M:%S %p %Z')
I also try to do this with datetime
and got another error:我也尝试使用
datetime
执行此操作,但出现另一个错误:
ValueError: time data 'Wednesday 06 November 2019 03:27:33 PM CDT' does not match format '%A %d %B %Y %I:%M:%S %p %Z'
What am I missing?我错过了什么?
Issue is with timezone, hard-coding timezone here works问题出在时区,硬编码时区在这里有效
import datetime
datetime.datetime.strptime('Wednesday 06 November 2019 03:05:42 PM CDT', '%A %d %B %Y %I:%M:%S %p CDT')
Although you could just hardcode 'CDT'
into your code, as @Hamza Rashid auggests in his answer , that will break if the timezone information ever changes to something else, such as 'CST'
or perhaps '-0600'
.尽管您可以将
'CDT'
硬编码到您的代码中,正如@Hamza Rashid 在他的回答中所暗示的那样,但如果时区信息更改为其他内容,例如'CST'
或可能是'-0600'
,它将中断。
To avoid that potential issue, I'd instead use something like the following, which just ignores everything in the string from the last space character in it onwards:为了避免这个潜在的问题,我会改用类似下面的东西,它只是忽略字符串中从最后一个空格字符开始的所有内容:
import datetime
date = 'Wednesday 06 November 2019 03:05:42 PM CDT'
date = datetime.datetime.strptime(date[:date.rindex(' ')], '%A %d %B %Y %I:%M:%S %p')
print(date) # -> 2019-11-06 15:05:42
