Python Coding challenge - Day 22| What is the output of the following Python Code?

Step-by-Step Explanation:

Initialization:

my_list is initialized as a list containing three elements: [1, 2, 3].

Using append:

The append method adds a single element to the end of a list.

Here, [4, 5] is a list, and it's treated as a single element.

After the append operation, my_list becomes [1, 2, 3, [4, 5]].

Notice that [4, 5] is now a sublist (nested list) within my_list.

Using len:

The len function returns the number of top-level elements in the list.

In my_list = [1, 2, 3, [4, 5]], there are four top-level elements:

1

2

3

[4, 5] (the entire sublist is considered one element).

Output:

The length of my_list is 4.

Final Output:

4
