Python datetime to string without microsecond component

Question

I m adding UTC time strings to Bitbucket API responses that currently only contain Amsterdam     time strings  For consistency with the UTC time strings returned elsewhere  the desired format is 2011-11-03 11 07 04  followed by  00 00  but that s not germane    What s the best way to create such a string  without a microsecond component  from a datetime instance with a microsecond component    gt  gt  gt  import datetime  gt  gt  gt  print unicode datetime datetime now    2011-11-03 11 13 39 278026   I ll add the best option that s occurred to me as a possible answer  but there may well be a more elegant solution   Edit  I should mention that I m not actually printing the current time     I used datetime now to provide a quick example  So the solution should not assume that any datetime instances it receives will include microsecond components

If you want to format a datetime object in a specific format that is different from the standard format  it s best to explicitly specify that format    gt  gt  gt  datetime datetime now   strftime   Y- m- d  H  M  S    2011-11-03 18 21 26    See the documentation of datetime strftime   for an explanation of the   directives

Yet another option    gt  gt  gt  import time  gt  gt  gt  time strftime   Y- m- d  H  M  S    2011-11-03 11 31 28    By default this uses local time  if you need UTC you can use the following    gt  gt  gt  time strftime   Y- m- d  H  M  S   time gmtime     2011-11-03 18 32 20

As of Python 3 6   the best way of doing this is by the new timespec argument for isoformat  isoformat timespec  seconds   sep       Usage   gt  gt  gt  datetime now   isoformat timespec  seconds    2020-10-16T18 38 21   gt  gt  gt  datetime now   isoformat timespec  seconds   sep       2020-10-16 18 38 35

Since not all datetime datetime instances have a microsecond component  i e  when it is zero   you can partition the string on a     and take only the first item  which will always work   unicode datetime datetime now    partition      0

This I use because I can understand and hence remember it better  and date time format also can be customized based on your choice   -  import datetime moment   datetime datetime now   print                     format moment day  moment month  moment year                                   moment hour  moment minute  moment second
