Answer: Python Puzzler #2849

The answer is B. The program prints:

grape

This answer was checked by running the program for real.

Why?

Python counts list positions from 0, so position 2 is the third item.

Trace table

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

positionnegative positionitem
0-6plum
1-5carrot
2-4grape
3-3mango
4-2melon
5-1apple

The code again

basket = ["plum", "carrot", "grape", "mango", "melon", "apple"]
print(basket[2])

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