This is a logic errors bug
The wrong operator, an inverted condition, a formula the right way round but backwards.
What went wrong: range(len(prices)) gives the positions 0, 1, 2. The loop adds 0 + 1 + 2 = 3.
The fix: for p in prices: (or return sum(prices))
Remember: for item in my_list gives you the items. Use enumerate() if you also need the position.
The pattern behind it: logic errors.
