Days and sales at the same position

A bakery's loaf sales by day are stored in two separate lists. The values at the same position are the record for the same day. Write what the code prints when it runs.

Code

days = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
loaves = [42, 38, 66, 51, 47, 59]

print(len(days), len(loaves))
peak = loaves.index(max(loaves))
print(peak, days[peak], loaves[peak])
print(days[peak + 1], loaves[peak + 1] - loaves[peak])
