Question

1. what will be displayed by the following code? matrix = 1, 2, 3, 4, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 for i in range(0, 4): print(matrixi0, end = \ \) 4 5 6 7 1 2 3 4 2 5 9 13 1 4 8 12 9. the %s symbols found within print functions are called: conversion specifiers sort list method nested loops join method

Explanation:

8.

Step1: Analyze the code logic

The code defines a 2 - D list (matrix) and then has a for loop that iterates 4 times. In each iteration, it prints the first element of each inner list of the matrix.

Step2: Identify the first elements

The first elements of the inner lists [1, 2, 3, 4], [4, 5, 6, 7], [8, 9, 10, 11], [12, 13, 14, 15] are 1, 4, 8, 12 respectively.

In Python, the %s symbol within print functions is used to specify that a string will be inserted at that position. It is a conversion specifier for string formatting.

Answer:

1 4 8 12
