Python Coding challenge - Day 185 | What is the output of the following Python Code?

 

Code:

x = [1, 2, 3]

x.insert(1, 4)

print(x)

Solution and Explanation: 

Let's break it down step by step:

Creating the list x:

x = [1, 2, 3]
Here, a list named x is created with three elements: 1, 2, and 3.
Inserting an element into the list:

x.insert(1, 4)
This line inserts the value 4 at index 1 in the list x. In Python, indexing starts from 0, so 1 refers to the second position in the list. This action shifts the original element at index 1 (which is 2) and all subsequent elements to the right.
Printing the modified list:

print(x)
This line prints the modified list x after the insertion operation.
So, the output of print(x) would be [1, 4, 2, 3]. The 4 is inserted at index 1, pushing 2 and 3 one position to the right.
