Python: Adds up columns and rows of given table as shown in the specified figure

Python Basic - 1: Exercise-63 with Solution

Your task is to develop a small part of spreadsheet software.
Write a Python program that adds up the columns and rows of the given table as shown in the specified figure:

Pictorial Presentation:

n (the size of row and column of the given table)
1st row of the table
2nd row of the table
:
:
n th row of the table
The input ends with a line consisting of a single 0.
Output:
For each dataset, print the table with sum of rows and columns.

Sample Solution:

Python Code:

while True:
    print("Input number of rows/columns (0 to exit)")
    n = int(input())
    if n == 0:
        break
    print("Input cell value:")
    x = []
    for i in range(n):
        x.append([int(num) for num in input().split()])

    for i in range(n):
        sum = 0
        for j in range(n):
            sum += x[i][j]
        x[i].append(sum)

    x.append([])
    for i in range(n + 1):
        sum = 0
        for j in range(n):
            sum += x[j][i]
        x[n].append(sum)
    print("Result:")
    for i in range(n + 1):
        for j in range(n + 1):
            print('{0:>5}'.format(x[i][j]), end="")
        print()

Sample Output:

Input number of rows/columns (0 to exit)
 4
Input cell value:
 25 69 51 26
 68 35 29 54
 54 57 45 63
 61 68 47 59
Result:
   25   69   51   26  171
   68   35   29   54  186
   54   57   45   63  219
   61   68   47   59  235
  208  229  172  202  811
Input number of rows/columns (0 to exit)
