Answer: Python Puzzler #2793

The answer is D. The program prints:

grape

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
0-5grape
1-4banana
2-3carrot
3-2apple
4-1plum

The code again

basket = ["grape", "banana", "carrot", "apple", "plum"]
print(basket[0])

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