Python Exercise: Generates a two-dimensional array

Python Conditional: Exercise-11 with Solution

Write a Python program that takes two digits m (row) and n (column) as input and generates a two-dimensional array. The element value in the i-th row and j-th column of the array should be i*j.
Note :
i = 0,1.., m-1
j = 0,1, n-1.

Sample Solution:

Python Code :

row_num = int(input("Input number of rows: "))
col_num = int(input("Input number of columns: "))
multi_list = [[0 for col in range(col_num)] for row in range(row_num)]

for row in range(row_num):
    for col in range(col_num):
        multi_list[row][col]= row*col

print(multi_list)

Sample Output:

Input number of rows: 3                                                                                       
Input number of columns: 4                                                                                    
[[0, 0, 0, 0], [0, 1, 2, 3], [0, 2, 4, 6]]

Previous: Write a Python program which iterates the integers from 1 to 50. For multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz".
Next: Write a Python program that accepts a sequence of lines (blank line to terminate) as input and prints the lines as output (all characters in lower case).
