Chapter 7: Problem 5

What will the following code display? numbers = [1, 2, 3, 4, 5] print(numbers[?2])

Short Answer

Expert verified
Answer: 4

Step by step solution

01

Analyze the list and the index

We have a list named "numbers", which contains the elements [1, 2, 3, 4, 5]. We are asked to print the value at the index "?2". However, there is an error. The correct syntax should be "-2" instead of "?2". So, let's work on the correct index: -2. In Python, negative indices refer to counting positions from the end of the list.
02

Find the element at index -2

Now that we discern how negative indexing works in Python lists, let's find the element at index -2. Since starting from the end of the list is represented by -1, the second last element is represented by -2. 1. -1 (last element) -> 5 2. -2 (second last element) -> 4
03

Print the element at index -2

The element at index -2 is 4. Therefore, the code with the corrected index (numbers[-2]) will display the value 4 when executed.
