"""Solution 16.4.2 — Releasing the scale

Chapter 16: Handling Failures — Everyday Programming

Bug type: Logical

“Scale released” must always print, but it is in the else block, which
runs only when no exception occurs; on bad input it is skipped. Use
finally so it runs whether or not an error happened.

Exercise: ex_16_4_2.py
