"""Solution 6.4.4 — Indexing the last item

Chapter 6: Objects — Everyday Programming

Bug type: Runtime

len(scores) is 4, but valid indexes are 0 through 3, so
scores[len(scores)] raises an IndexError. The last item is at
scores[len(scores) - 1], or more simply scores[-1].

Exercise: ex_6_4_4.py

scores = [91, 87, 95, 78]
latest = scores[-1]
print(latest)   # 78
