4, 5, 6, 7,
8, 9, 10, 11,
12, 13, 14, 15

for i in range(0, 4):
print(matrixi2, end = \ \)

o 3 6 10 14
o 8 9 10 11
o 2 5 9 13
o 4 5 6 7

Explanation:

Question 13

Step1: Understand the matrix

The given matrix is a 4 - by - 4 list of lists in Python.

Step2: Analyze the loop

The for loop iterates from i = 0 to i=3. For each i, it prints the element at index 2 (third element as indexing starts from 0) of the i - th sub - list of the matrix.
When i = 0, matrix[0][2]=3; when i = 1, matrix[1][2]=6; when i = 2, matrix[2][2]=10; when i = 3, matrix[3][2]=14.

In Python, the input() function is used to capture string data entered from the keyboard. The print() function is for outputting data, str() is for converting other data types to strings, and upper() and lower() are for converting strings to uppercase and lowercase respectively.

Answer:

3 6 10 14
