Python Coding challenge - Day 7| What is the output of the following Python Code?

 

Code Explanation:

my_list = [1, 2, 3, 4, 5]

This line creates a list called my_list, which contains the numbers [1, 2, 3, 4, 5].

In Python, a list is an ordered collection of items, and each item in the list has an index that represents its position.

result = my_list[-3:-1]

This line uses list slicing to create a sublist from my_list.

Negative indices are used here:

-3: Refers to the third element from the end of the list. Since the list is [1, 2, 3, 4, 5], the third-to-last element is 3.

-1: Refers to the last element of the list. So, my_list[-1] is 5, but in slicing, the stop index (-1 here) is excluded. That means the slice will stop right before 5.

The slice starts at the element at index -3 (which is 3), and it goes up to but does not include the element at index -1 (which is 5). So, it includes the elements at indices -3 (3) and -2 (4), which results in the sublist [3, 4].

print(result)

This line prints the sublist result, which contains [3, 4].

Summary:

You started with the list [1, 2, 3, 4, 5].

Using negative indices, you sliced the list starting from the third-to-last element (3) and stopping just before the last element (5), giving you [3, 4].

The output is:

[3, 4]
