Subtract Two DateTime objects – Python

Subtract Two DateTime objects – Python

When you subtract two datetime objects in python, you get a datetime.timedelta object. You can then get the total_seconds() for that timedelta object and check if that is greater than 3*3600 , which is the number of seconds for 3 hours. Example –

>>> a = datetime.datetime.now()
>>> b = datetime.datetime(2015,8,25,0,0,0,0)
>>> c = a - b
>>> c.total_seconds()
87062.729491
>>> c.total_seconds() > 3*3600
True

You can also just compare to another timedelta object

import datetime
if c >= datetime.timedelta(hours=3):
   #do something

You can do this

three_hours = 3600*3 # in seconds

if c.total_seconds() >= three_hours:
    # do stuff
