Python Coding challenge - Day 28 | What is the output of the following Python code?

 

In the above code a list a initially defined as [2, 5, 3, 4]. Then, you are trying to insert the value 2 into the list at index 2:2, which is essentially inserting it at position 2 without replacing any existing elements. Here's what happens step by step:

a is initially defined as [2, 5, 3, 4].

a[2:2] = [2] inserts the value 2 into the list a at position 2 without replacing any existing elements.

When you print a, it will display the modified list.

So, when you print a after this operation, you will get the following output: [2, 5, 2, 3, 4]

The value 2 has been inserted at index 2, and the elements after index 2 have been shifted to accommodate the new value.
