Answer: Python Puzzler #832

The answer is B. The program prints:

carrot
What the program prints
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
0-5mango
1-4pear
2-3carrot
3-2apple
4-1grape

The code again

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

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