PROGRAM EXPLANATION

Algorithm and explanation

  1. Initialize the sample values used to use a custom print separator.
  2. Apply print() and sep to compute the required result.
  3. Display the result for use a custom print separator and compare it with the documented sample output.

This example of use a custom print separator computes the result directly from the prepared sample data. It demonstrates print() and sep and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For use a custom print separator, keep the data shape and value types consistent with print().

Check this

Apply print() in the same order shown by the algorithm; changing the order can change the result.

Check this

Verify the final print() and sep 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.
