Given the following Python script:

print(a[0])

What is the output of this print command?

Show Suggested Answer Hide Answer
Suggested Answer: A

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.


Python Official Documentation: Covers list indexing and operations.

Python Programming Tutorials: Provide examples of list indexing.

Wait, is this a trick question? I'm going with C, 7. The array looks like it's index-based, right?

I think the output is A) 1 because the index starts at 0.

Easy peasy, the output is 1. Arrays in Python start at index 0, so a[0] is the first element.
