PROGRAM EXPLANATION
Algorithm and explanation
- Import the required standard-library tools and prepare the sample data for format a date.
- Apply datetime and strftime() to compute the required result.
- 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.
