Python program to Multiply two integers|in 5ways

In this tutorial, we will discuss the Python program to Multiply two integers|in 5ways

In this post, we are going to learn how to find multiplication of two numbers via different 5 ways in Python language

Program to Multiply two integers

Program to Multiply two integers – standard method

Program 1

#Python program to mutipy two numbers
num1=15
num2=16
mul=num1 * num2;
print("Multiplication of two numbers: ",mul)

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

Multiplication of two numbers:  240

• Integer variable num1 and num2 both are declared and initialized
• the num1 and num2 both are multiplied together and the value is assigned to the integer variable mul
• finally the program is displayed the output using print() function

Program to Multiply two integers – using user input

Program 2

#Python program to mutipy two numbers
num1=int(input("Enter first number: "))
num2=int(input("Enter second number: "))
#input numbers from the user

mul=num1 * num2;#caculate multipication

print("Multipication of two numbers: ",mul)
#display output

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

Enter first number: 12
Enter second number: 24
Multiplication of two numbers:  288

 

Approach

• Integer variable num1 and num2 both are declared,
• The program takes input from the user
• Then the user enters the input value for num1, num2
• the program will read the input and store the variables in num1, num2.
• the num1 and num2 both are multiplied together and the value is assigned to the integer variable mul
• finally the program is displayed the output using print() function
  

 

Program to Multiply two integers – using function

Program 3

#Python program to multiply two numbers using function

def multiply(num1,num2):#function definition
    product=num1 * num2
    return product

num1=int(input("Enter first number "))
num2=int(input("Enter second number "))
#input numbers from the user

result=multiply(num1,num2)#caling the function

print("Multipication of two numbers: ",result)
#display output

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

Enter first number 12
Enter second number 21
Multiplication of two numbers:  252

 

Approach

• Integer variable num1 and num2 both are declared,
• The program takes input from the user
• Then the user enters the input value for num1, num2
• the program will read the input  store the variables in num1, num2.
• define the function for find product of two numbers
• When we call the function, the num1 and num2 both are multiplied together
• Then the value is assigned to the integer variable result
• finally the program is displayed the output using print() function

 

Program to Multiply two integers – using recursion

Program 4

def product(x,y):
    if(x<y):
        return product(y,x)
    elif(y!=0):
        return (x+product(x,y-1))
    else:
        return 0

x=int(input("Enter first number: "))
y=int(input("Enter second number: "))

print("Product is ", product(x,y))

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

Enter first number: 100
Enter second number: 50
('Product is ', 5000)

Approach

• Integer variable x and y both are declared,
• The program takes input from the user
• Then the user enters the input value for x and y
  
• the program will read the input  store the variables in  x , y.
• define the recursive function for multiply two numbers
• When we call the function, the x and y both are multiplied recursively
• finally the program is displayed the output using print() function

 

Program to Multiply two integers – using without * operator

Program 5

num1=int(input("Enter first number: "))
num2=int(input("Enter second number: "))
product=0
for i in range(1,num2+1):
    product=product+num1
print("Product is ", product)

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

Enter first number: 50
Enter second number: 60
Product is 3000
