PROGRAM EXPLANATION

Algorithm and explanation

Initialize the sample values used to define a simple function.
Apply def and return to compute the required result.
Display the result for define a simple function and compare it with the documented sample output.

This example of define a simple function computes the result directly from the prepared sample data. It demonstrates def and return and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For define a simple function, keep the data shape and value types consistent with def.

Check this

Keep every dependent statement inside the correct indented Python block.

Check this

Verify the final def and return 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.
