Python Coding challenge - Day 175 | What is the output of the following Python Code?

 

Code:

x = [1, 2, 3]

y = [4, 5, 6]

z = [x, y]

print(z[0][1])

Solution and Explanation:

Let's break down the code step by step:

x = [1, 2, 3]: This line creates a list named x containing the elements 1, 2, and 3.

y = [4, 5, 6]: This line creates another list named y containing the elements 4, 5, and 6.

z = [x, y]: Here, a list named z is created, containing two lists: x and y. So, z becomes [[1, 2, 3], [4, 5, 6]].

print(z[0][1]): This line prints the element at index 1 of the first list in z. Since z[0] refers to [1, 2, 3] and z[0][1] refers to the element at index 1 of that list, the output will be 2.
