Answer: Python Puzzler #830

The answer is D. The program prints:

mango
What the program prints
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
0-4banana
1-3mango
2-2pear
3-1grape

The code again

basket = ["banana", "mango", "pear", "grape"]
print(basket[1])

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