[All JN0-223 Questions]
Topic #: 2
Given the following Python script:
a = [1,2,3,4,5,6,7,8,9]
print(a[0])
What is the output of this print command?
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.
