Answer: Python Puzzler #807

The answer is B. The program prints:

banana
What the program prints
Checked by running the program for real.

Why?

Python counts list positions from 0, so position 2 is the third item.

Trace table

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

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

The code again

basket = ["grape", "apple", "banana", "plum", "mango"]
print(basket[2])

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