Answer by officialrahulmandal for Converting string into datetime

If you don't want to explicitly specify which format your string is in with respect to date time format you can use this hack to by pass that step :-

from dateutil.parser import parse# function that'll guess the format and convert it into python datetime formatdef update_event(start_datetime=None, end_datetime=None, description=None):    if start_datetime is not None:        new_start_time = parse(start_datetime)        return new_start_time#sample input dates in different formatd = ['06/07/2021 06:40:23.277000','06/07/2021 06:40','06/07/2021']new = [update_event(i) for i in d]for date in new:    print(date)    # sample output dates in python datetime object    # 2014-04-23 00:00:00    # 2013-04-24 00:00:00    # 2014-04-25 00:00:00

If you want to convert it into some other datetime format just modify the last line with the format you like for example something like date.strftime('%Y/%m/%d %H:%M:%S.%f') :-

from dateutil.parser import parsedef update_event(start_datetime=None, end_datetime=None, description=None):    if start_datetime is not None:        new_start_time = parse(start_datetime)        return new_start_time#sample input dates in different formatd = ['06/07/2021 06:40:23.277000','06/07/2021 06:40','06/07/2021']# passing the dates one by one through the functionnew = [update_event(i) for i in d]for date in new:    print(date.strftime('%Y/%m/%d %H:%M:%S.%f'))    # sample output dates in required python datetime object    #2021/06/07 06:40:23.277000    #2021/06/07 06:40:00.000000    #2021/06/07 00:00:00.000000

try running the above sniipet to have a btter clarity. Thanks
