如何使用python strptime和strftime将2017-02-09T09：43：04.216 + 1000等日期时间格式转换为2017年2月9日？

Question

I have some created and updated datetime coming in dynamically from JIRA API for an automation process for getting JIRA tickets on a monthly basis using a python script to load into an excel sheet.

Some of the sample dates are as follows:

1. 2017-02-09T09:33:33.508+1100
2. 2017-05-19T13:59:36.735+1000

What I would like to present this is in a format like %d-%b-%Y (ex: 09-Feb-2017)

I have tried using python datetime.strptime and strftime .

Sample code as below:

from datetime import datetime

datetimeObj = datetime.strptime('2017-02-09T09:43:04.216+1000', '%Y-%m-%dT%H:%M:%S.%f+1000')

print(datetimeObj.strftime('%d-%b-%Y'))

This gives me the result as expected but now I have hardcoded the values like date I wanted and in the datetime format I have added +1000 but since its dynamically changing datetime I get stuck when the datetime ends with values such as +1100 .

I believe the last part is something to do with the daylight savings but I am not able find the right format for this in this case.

Is there anyway to convert the datetime format for this for the last +1000 and +1100 part instead of hardcoding like '%Y-%m-%dT%H:%M:%S.%f+1000' like this?

Answer 1

seems you already figured out a solution but if this is always the format..

you can do:

date = '2017-02-09T09:33:33.508+1100'

d = re.search('[0-9]+-[0-9]+-[0-9]+',date).group()
d = re.search('([0-9]+-)+[0-9]+',date).group()
d = date.split('T')[0]
d = date[0:10]

or some variant of this...then:

print(datetime.strptime(d,'%Y-%m-%d').strftime('%d-%b-%Y'))

or

print(datetime.strptime(''.join(re.findall('\d+',date)[0:3]),'%Y%m%d').strftime('%d-%b-%Y'))

:)

Just found an answer to this. Hope this may help others too if someone else is stuck like me.

from datetime import datetime

datetimeObj = datetime.strptime('2017-02-09T09:43:04.216+1000', '%Y-%m-%dT%H:%M:%S.%f%z')

print(datetimeObj.strftime('%d-%b-%Y'))

Using %z will solve the problem.

%z is UTC offset in python strftime() and strptime() in the form +HHMM or -HHMM (empty string if the the object is naive).

This helps when there are values such as (empty), +0000, -0400, +1030 at the end of time format.
