Answer: Python Puzzler #2481

The answer is D. The program prints:

pear

This answer was checked by running the program for real.

Why?

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

Trace table

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

positionnegative positionitem
0-4pear
1-3mango
2-2banana
3-1grape

The code again

basket = ["pear", "mango", "banana", "grape"]
print(basket[0])

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