"""Solution 16.1.5 — Validating a test score

Chapter 16: Handling Failures — Everyday Programming

Bug type: Logical

The except block silently keeps the invalid text by assigning score =
raw, so the program reports nonsense as a score instead of rejecting it.
Validation should re-prompt or refuse bad input rather than swallow it.

Exercise: ex_16_1_5.py
