Question

1. what will be displayed by the following code?

data = 1, 2, 3, 4, 5, 6, 7, 8

5
3
7
8
4

1. what will be displayed by the following program?

values = 8, 7, 1, 2 , 5, 3, 9, 4
for row in values:
row.sort()
for element in row:
print(element, end = \ \)
print()
the program prints two rows: 1 2 7 8 followed by 3 4 5 9
the program prints two rows: 8 7 1 2 followed by 5 3 9 4
the program prints one row: 1 2 3 4 5 7 8 9
the program prints one row: 8 7 1 2 3 4 5 9
the program prints two rows: 1 2 7 8 followed by 5 3 9 4

Explanation:

Step1: Analyze first code indexing

The data list is a 3 - dimensional list. data[1] accesses the second sub - list [[5, 6], [7, 8]], data[1][1] accesses the second sub - list [7, 8] of [[5, 6], [7, 8]], and data[1][1][0] accesses the first element of [7, 8] which is 7.

Step2: Analyze second code sorting and printing

The outer for loop iterates over each row in the values list. The row.sort() method sorts each row in ascending order. The inner for loop prints each element of the sorted row with a space between elements, and the print() after the inner loop moves to the next line. So the first row [8, 7, 1, 2] becomes [1, 2, 7, 8] and the second row [5, 3, 9, 4] becomes [3, 4, 5, 9] after sorting, and the program prints two rows: 1 2 7 8 followed by 3 4 5 9.

Answer:

1. C. 7
2. A. The program prints two rows: 1 2 7 8 followed by 3 4 5 9
