Python Coding challenge - Day 177 | What is the output of the following Python Code?

 

Code:

x = [1, 2, 3]

y = [4, 5, 6]

z = [x, y]

print(z[1][1])

Solution and Explanation: 

 Let's break it down step by step:

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

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

z = [x, y]: This line creates a list named z containing x and y as its elements. So, z is a list of lists, where the first element is the list x and the second element is the list y.

print(z[1][1]): This line prints the element at index 1 of the list at index 1 in z.

Breaking it down further:

z[1] accesses the second element of z, which is the list y.

z[1][1] accesses the element at index 1 of the list y.

So, the output of this code will be 5, because 5 is the element at index 1 of the list y.
