View Answer

Answer: A

Explanation:

In Python, lists are zero-indexed, meaning the first element of the list is at index 0. The given script is:

pythona = [1, 2, 3, 4, 5, 6, 7, 8, 9]

print(a[0])

a[0] refers to the first element in the list a, which is 1.

So, the output of the print(a[0]) command is 1.

Option A is correct because Python indexing starts at 0, making the first element of the list at index 0.
