PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to use the assignment expression.
  2. Apply Walrus operator and Assignment expression to compute the required result.
  3. Display the result for use the assignment expression and compare it with the documented sample output.

This example of use the assignment expression computes the result directly from the prepared sample data. It demonstrates Walrus operator and Assignment expression and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For use the assignment expression, keep the data shape and value types consistent with Walrus operator.

Check this

Keep every dependent statement inside the correct indented Python block.

Check this

Verify the final Walrus operator and Assignment expression 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.
