PROGRAM EXPLANATION

Algorithm and explanation

Initialize the sample values used to use the loop else clause.
Process the data step by step using for-else and break.
Display the result for use the loop else clause and compare it with the documented sample output.

This example of use the loop else clause processes the sample values in a controlled iteration. It demonstrates for-else and break and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For use the loop else clause, keep the data shape and value types consistent with for-else.

Check this

Keep every dependent statement inside the correct indented Python block.

Check this

Verify the final for-else and break 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.
