PROGRAM EXPLANATION

Algorithm and explanation

Initialize the sample values used to use try else and finally.
Execute the operation safely with try and else.
Display the result for use try else and finally and compare it with the documented sample output.

This example of use try else and finally protects the operation with explicit exception handling. It demonstrates try, else, and finally and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For use try else and finally, keep the data shape and value types consistent with try.

Check this

Keep every dependent statement inside the correct indented Python block.

Check this

Check denominators, numeric ranges and rounding before comparing the calculated value.

Try it yourself

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