What is the standard way to add N seconds to datetime.time in Python?

To add N seconds to a datetime.time object in Python, you need to convert the time to a datetime.datetime object, perform the addition, and then convert it back to a datetime.time object. Python's datetime module provides the necessary tools to accomplish this. Here's the standard way to do it:

from datetime import time, datetime, timedelta # Create a time object original_time = time(12, 30, 0) # Convert the time to a datetime object with a dummy date (e.g., January 1, 1900) dummy_date = datetime(1900, 1, 1, original_time.hour, original_time.minute, original_time.second) # Add N seconds to the datetime object N = 60 # Replace with the number of seconds to add result_datetime = dummy_date + timedelta(seconds=N) # Convert the result back to a time object result_time = result_datetime.time() print("Original Time:", original_time) print(f"Added {N} Seconds:", result_time)

In this code:

  1. We create an original_time object representing the initial time.

  2. We convert the original_time to a datetime object by creating a dummy_date with the same hour, minute, and second components. We use a dummy date because datetime objects require a date component.

  3. We add N seconds to the dummy_date using timedelta to perform the time addition.

  4. Finally, we extract the resulting time as a time object using .time() and store it in result_time.

Now, result_time contains the original_time plus N seconds. Make sure to replace N with the number of seconds you want to add.
