The answer is C. The program prints:
mango
This answer was checked by running the program for real.
Why?
A negative position counts from the end: -1 is the last item, -2 the one before it. So -4 means item number 4 from the end.
Trace table
A trace table follows the program step by step. Here’s this one:
| position | negative position | item |
|---|---|---|
| 0 | -4 | mango |
| 1 | -3 | carrot |
| 2 | -2 | grape |
| 3 | -1 | plum |
The code again
basket = ["mango", "carrot", "grape", "plum"]
print(basket[-4])Try it: change one number in the program and predict the new output before you run it.
