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?
>>> import datetime >>> 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:
>>> import datetime >>> 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.
>>> import datetime >>> now = datetime.datetime.now() >>> print unicode(now.replace(microsecond=0)) 2011-11-03 11:19:07 In Python 3.6:
from datetime import datetime datetime.now().isoformat(' ', 'seconds') '2017-01-11 14:41:33' This is the way I do it. ISO format:
import datetime datetime.datetime.now().replace(microsecond=0).isoformat() # Returns: '2017-01-23T14:58:07' You can replace the 'T' if you don't want ISO format:
datetime.datetime.now().replace(microsecond=0).isoformat(' ') # Returns: '2017-01-23 15:05:27' Yet another option:
>>> import time >>> 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:
>>> time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime()) '2011-11-03 18:32:20' Keep the first 19 characters that you wanted via slicing:
>>> str(datetime.datetime.now())[:19] '2011-11-03 14:37:50' I usually do:
import datetime now = datetime.datetime.now() now = now.replace(microsecond=0) # To print now without microsecond. # To print now: print(now) output:
2019-01-13 14:40:28 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] As of Python 3.6+, the best way of doing this is by the new timespec argument for isoformat.
isoformat(timespec='seconds', sep=' ') Usage:
>>> datetime.now().isoformat(timespec='seconds') '2020-10-16T18:38:21' >>> datetime.now().isoformat(timespec='seconds', sep=' ') '2020-10-16 18:38:35' We can try something like below
import datetime date_generated = datetime.datetime.now() date_generated.replace(microsecond=0).isoformat(' ').partition('+')[0] f-string formatting
>>> import datetime >>> print(f'{datetime.datetime.now():%Y-%m-%d %H:%M:%S}') 2021-12-01 22:10:07 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)) >>> from datetime import datetime >>> dt = datetime.now().strftime("%Y-%m-%d %X") >>> print(dt) '2021-02-05 04:10:24' I found this to be the simplest way.
>>> t = datetime.datetime.now() >>> t datetime.datetime(2018, 11, 30, 17, 21, 26, 606191) >>> t = str(t).split('.') >>> t ['2018-11-30 17:21:26', '606191'] >>> t = t[0] >>> t '2018-11-30 17:21:26' >>> You can also use the following method
import datetime as _dt ts = _dt.datetime.now().timestamp() print("TimeStamp without microseconds: ", int(ts)) #TimeStamp without microseconds: 1629275829 dt = _dt.datetime.now() print("Date & Time without microseconds: ", str(dt)[0:-7]) #Date & Time without microseconds: 2021-08-18 13:07:09 Current TimeStamp without microsecond component:
timestamp = list(str(datetime.timestamp(datetime.now())).split('.'))[0]
