In this tutorial, we will discuss the concept of  multiplying two numbers without using arithmetic operator in Python language. 

In this post, we will learn how to get the product of two number without arithmetic operator in Python programming language

 

Python program to find product of two numbers

Using for loop – Program 1

This program is used to find the multiplication of two numbers entered by the user – using for loop without arithmetic operator

#How to print product of two numbers without using "*" operator in Python
num1=int(input("Enter a number for num1: "))#get input from user for num1
num2=int(input("Enter a number for num2: "))#get input from user for num2
product=0
for i in range (1,num2+1):  #Python for loop
 product=product+num1       #product+=num1
print("Multiplication of numbers: ",product) #Display multiplication of numbers

When the above code is executed, it produces the following result

Enter a number for num1: 25
Enter a number for num2: 50
Multiplication of numbers: 1250

 

Using function – Program 2

This program is used to find the multiplication of two numbers entered by the user – using if elif statements without arithmetic operator

x=int(input("Enter a number for x: "))#get input from user for x
y=int(input("Enter a number for y: "))#get input from user for y


def findProduct(x,y):  #Python function
    if y<0:
        return -findProduct(x,-y)
    elif y == 0:
        return 0
    elif y == 1:
        return x
    else:
         return x+ findProduct(x,y-1)
print("product of two numbers: ",findProduct(x,y))
#Display result on the screen

When the above code is executed, it produces the following result

Enter a number for x: 30
Enter a number for y: 12
product of two numbers: 360
