PROGRAM EXPLANATION

Algorithm and explanation

  1. Import the required standard-library tools and prepare the sample data for format a date.
  2. Apply datetime and strftime() to compute the required result.
  3. Display the result for format a date and compare it with the documented sample output.

This example of format a date computes the result directly from the prepared sample data. It demonstrates datetime and strftime() and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For format a date, keep the data shape and value types consistent with datetime.

Check this

Apply datetime in the same order shown by the algorithm; changing the order can change the result.

Check this

Verify the final datetime and strftime() result against the sample before trying new data.

Try it yourself

Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
