Chapter 8: Problem 5

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

Short Answer

Expert verified
```python numbers = [1, 2, 3, 4, 5] print(numbers[-2]) ``` Answer: The output of the code snippet will be 4.

Step by step solution

01

Understand Python list indexing

Python list indexing provides a way to access any element in the list by its position. The elements in a list have positions starting from zero. So, in this example, the position of 1 is 0, the position of 2 is 1, and so on. Negative indexing is also possible, and it starts from the end of the list. So, the last element has an index of \(-1\), the second last element has an index of \(-2\), and so on.
02

Determine the element at the specific index

We are given the index \([-2]\) which implies the second last element. The 'numbers' list is [1, 2, 3, 4, 5], so the second last element in this list is 4.
03

Write down the output

The print function will output the value at the given index, which, in this case, is 4. So, the output of the given code will be: \\[4\\]
