Python: Convert timedelta to milliseconds - thisPointer

This article will discuss how we can convert the datetime module's timedelta object to total milliseconds in python. Skiptocontent Thisarticlewilldiscusshowwecanconvertthedatetimemodule’stimedeltaobjecttototalmillisecondsinpython. Background: InPython’sdatetimemodule,thedatetime.timedeltarepresentsthedurationbetweentwodates,time,ordatetimeobjects.Forexample,wehavetwotimestampsasdatetimeobjects, fromdatetimeimportdatetime timestamp_1=datetime(2019,6,3,8,12,16,100000) timestamp_2=datetime(2019,6,3,9,17,11,200002) Ifyouwantthedifferencebetweenthesetwotimestamps,youcansubtractthesetwodatetimeobjects.Itwillgiveatimedeltaobjecti.e. #Getdifferentbetweentwodatetimeastimedeltaobject. diff=(timestamp_2-timestamp_1) print(diff) print(type(diff)) Output: 1:04:55.100002 Thistimedeltaobjectcontainsthetimedifferencebetweentwodatetimeobjects.Butifyouprintit,thenyouwillgettheabsolutedifferencebetweentwodatetimesinhh:mm::ss.ffffffformat.Whatif,youwantthecompletedurationintotalmillisecondsonly?Forthatwecanconvertthistimedeltaobjecttomillisecondsonly.Let’sseehowtodothat, Advertisements Converttimedeltatomillisecondsinpython Thetimedeltaobjectrepresentsadurationbetweentotimestamps.Ithasafunctiontotal_seconds(),whichgivesthetotalsecondsinthedurationpointedbytimedeltaobject.Wecanmultiplyitby1000,togetthecompletedurationinmilliseconds.Forexample, #ConverttimedeltaobjecttoMilliseconds diff_in_milliseconds=diff.total_seconds()*1000 print("TotalTimeDifference:{}Milliseconds".format(diff_in_milliseconds)) Output: TotalTimeDifference:3895100.0020000003Milliseconds Wegotthedifferencebetweentwotimestampsinmillisecondsonlybyconvertingtimedeltatomilliseconds.
