Answer: Python Puzzler #2450

The answer is B. The program prints:

apple

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
0-4mango
1-3apple
2-2melon
3-1banana

The code again

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

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