python datetime time difference code example

Example 1: python difference in time

from datetime import datetime
import time

datetime1 = datetime.datetime.now()
# Wait for 1 minute
time.sleep(60) 
datetime2 = datetime.datetime.now()

difference = datetime2 - datetime1
print(f"The time difference between the 2 time is: {difference}")

Example 2: time difference between two datetime.time

# Create datetime objects for each time (a and b)
dateTimeA = datetime.datetime.combine(datetime.date.today(), a)
dateTimeB = datetime.datetime.combine(datetime.date.today(), b)
# Get the difference between datetimes (as timedelta)
dateTimeDifference = dateTimeA - dateTimeB
# Divide difference in seconds by number of seconds in hour (3600)  
dateTimeDifferenceInHours = dateTimeDifference.total_seconds() / 3600

Example 3: python datetime difference in seconds

import datetime as dt

a = dt.datetime(2013,12,30,23,59,59)
b = dt.datetime(2013,12,31,23,59,59)

(b-a).total_seconds()
