Answer:
40
Step-by-step explanation:
Indexes for arrays in Python start at 0, which means the first item of an array is at index 0, the second item is at index 1, the third item is at index 2, and the fourth item is at index 3.
Therefore when my_list[3] is put inside the print function, the fourth item, 40, is printed to the screen.
Hope this helps!
