Answer: Python Puzzler #2399

The answer is B. The program prints:

banana

This answer was checked by running the program for real.

Why?

Python counts list positions from 0, so position 1 is the second item.

Trace table

A trace table follows the program step by step. Here’s this one:

positionnegative positionitem
0-4melon
1-3banana
2-2apple
3-1plum

The code again

basket = ["melon", "banana", "apple", "plum"]
print(basket[1])

Try it: change one number in the program and predict the new output before you run it.
