datetime.timedelta

The `timedelta` class in Python represents a duration of time, such as a difference between two dates or times. It is used to perform arithmetic operations on dates and times.

A `timedelta` object is created using the `datetime.timedelta()` constructor, which takes arguments such as days, hours, minutes, seconds, microseconds, and milliseconds.

For example:

import datetime

# create a timedelta object representing 1 day
one_day = datetime.timedelta(days=1)

# create a timedelta object representing 2 hours
two_hours = datetime.timedelta(hours=2)

# add the two timedelta objects together
total_time = one_day + two_hours

# print the total time in seconds
print(total_time.total_seconds())

Output:

93600.0

In this example, we created two `timedelta` objects representing one day and two hours, and then added them together to get a total time of 26 hours. We then printed the total time in seconds using the `total_seconds()` method.
