TimeDelta - Time Travel with timedelta

In Python, timedelta is a class in the datetime module that represents a duration of time, such as the difference between two dates or times. A timedelta object is created using the timedelta() constructor, which takes several arguments to specify the duration.

Here's an example that demonstrates how to use timedelta in Python:

import datetime

# Create a timedelta object representing a duration of 1 day

one_day = datetime.timedelta(days=1)

# Create a datetime object for March 8, 2023 at 2:30 PM

dt1 = datetime.datetime(2023, 3, 8, 14, 30)

# Add the duration of 1 day to the datetime object

dt2 = dt1 + one_day

# Print the result

print(dt1) # Output: 2023-03-08 14:30:00

print(dt2) # Output: 2023-03-09 14:30:00

In this example, we first create a timedelta object representing a duration of 1 day using the days argument. We then create a datetime object for March 8, 2023 at 2:30 PM. Finally, we add the timedelta object to the datetime object using the + operator to create a new datetime object that represents the same time on the following day.

We can also perform arithmetic operations with timedelta objects, such as subtracting two datetime objects to calculate the duration between them. Here's an example:

import datetime

# Create two datetime objects representing different times

dt1 = datetime.datetime(2023, 3, 8, 14, 30)

dt2 = datetime.datetime(2023, 3, 9, 16, 45)

# Calculate the duration between the two datetime objects

duration = dt2 - dt1

# Print the result

print(duration) # Output: 1 day, 2:15:00

In this example, we create two datetime objects representing different times, and then subtract one from the other using the - operator to obtain a timedelta object representing the duration between them. We can then print this timedelta object to display the duration in a human-readable format.

Overall, timedelta objects are useful for performing arithmetic operations with dates and times in Python, such as adding or subtracting durations of time from datetime objects or calculating the duration between two datetime objects.
