Find if 24 hrs have passed between datetimes

Question

I have the following method:

# last_updated is a datetime() object, representing the last time this program ran
def time_diff(last_updated):
    day_period =         


        

Answer 1

Just to clear our some things, because I don't think all of us make use of the time Python lib. When you use datetime, which is especially in Django a very common practice, if you do the comparison like this:

if (now - then) > DAY:

it will hugely fail. This is because you can't compare datetime.timedelta to int.

The solution to this is to convert your objects to seconds.
For example:

from datetime import datetime

then = datetime_object
now = datetime.now()

if (now - then).total_seconds() > NUMBER_OF_SECONDS:
    # do something

Hope I helped out whoever faced issues on that.
