Answer: Python Puzzler #2495

The answer is D. The program prints:

carrot

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
0-6carrot
1-5melon
2-4apple
3-3plum
4-2pear
5-1mango

The code again

basket = ["carrot", "melon", "apple", "plum", "pear", "mango"]
print(basket[0])

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