Write it. Run it. Understand it.

Define reusable helpers, pass different arguments, and return results your caller can use. Verify each case in real Python.

CHALLENGE 01 / 6 · BEGINNER

Return a reusable hostname label

The fictional Northstar inventory needs consistent uppercase hostname labels. Fix label_host() so it returns an uppercase trimmed hostname rather than printing it. Store both call results in first and second; print them on separate lines as 'SW-01' and 'AP-02'. The function must work on two different inputs.

EXPECTED OUTPUT

SW-01
AP-02
