Answer: Python Puzzler #2795

The answer is A. The program prints:

pear

This answer was checked by running the program for real.

Why?

Python counts list positions from 0, so position 3 is the fourth item.

Trace table

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

positionnegative positionitem
0-5banana
1-4apple
2-3grape
3-2pear
4-1plum

The code again

basket = ["banana", "apple", "grape", "pear", "plum"]
print(basket[3])

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