Python Program to Create Mathematical Table of an Integer

Multiplication table in mathematics is a list of multiples of a number from 1 to 10. According to Wikipedia, the Multiplication table is a mathematical table used to define a multiplication operation for an algebraic system.

Procedure 

Initially, the number whose multiplication table is to be displayed is received as input. 

Then a list of multiples(up to 10) of the number is created by calling the function multiTable(num), with the received input as argument. Suppose the received input from the user is 7. In that case, the following list is created.

prodList = [1, 14, 21, 28, 35, 42, 49, 56, 63, 70 ]

Afterward, a counter(index) is added to the iterable(here prodList) using enumerate() method; which in turn returns as enumerate object. Finally, the multiplication table is printed based on the counter and the iterable.

Source Code

prodList = []

def multiTable(num):

    """"

    Creates a list of multiples of a number received as input 

    """

    global prodList

    for i in range(1, 11):

        prod = num * i

        prodList.append(prod)

  

num = int(input('Enter the number whose multiplication table is to be displayed: '))

multiTable(num)

print(prodList)

print('\n')

print('The multiplication table for {0} is:' .format(num))

for index, ele in enumerate(prodList, 1): # Creates multiplication table of a number

    print('{0} x {1} = {2}' .format(index, num, ele))

Output

Enter the number whose multiplication table is to be displayed: 70
[70, 140, 210, 280, 350, 420, 490, 560, 630, 700]


The multiplication table for 70 is:
1 x 70 = 70
2 x 70 = 140
3 x 70 = 210
4 x 70 = 280
5 x 70 = 350
6 x 70 = 420
7 x 70 = 490
8 x 70 = 560
9 x 70 = 630
10 x 70 = 700

Update:

The program can be optimised by using list comprehension to create a list of multiples of the number received as user input. Consequently, the function multiTable() can be eliminated. 

The updated source code:

Updated Source Code

import time

try:
    start = time.time()
    prodList = []
    num = int(input('Enter the number whose multiplication table is to be displayed: '))
    prodList = [num * i for i in range(1, 13)] #list comprehension to create a list of multiples of number received as input
    print(prodList)
    aster = '*'
    print(aster * 80)
    
    print('The multiplication table for {0} is:' .format(num))
    for index, ele in enumerate(prodList, 1): #Prints multiplication table of the number
        print('{0} x {1} = {2}' .format(index, num, ele))
        
    print(aster * 80)
    print ('Time to run program: ' +str(time.time()-start)) 
    
except(ValueError):
    print('Please enter a valid integter number')
