In this article, we will learn about python program to multiply two numbers with examples
Getting Started
The task is to get product of two numbers in python using python programming language. For example,
If a = 10 and b = 2. Then, product is 10 * 2 = 20.
We can do so in multiple ways –
 Simple Approach
 Using User Input
 Using User Input(Command Line Arguments)
 Using Lambda
 Using Function
Simple Approach
We can simply multiply two number using multiplication operator (i.e. * operator) in python as shown below –
m = 10 n = 30 result = m * n # Multiply using * operator print("Multiply = ", result)
Output:
Multiply = 300
Using User Input
If we want to take user input, we can do so using input() builtin function in python. Then, we typecast input value into integer value using int.
Finally, we get product of two numbers in python using * operator.
m = int(input("Enter a number")) n = int(input("Enter another number")) result = m * n print("Multiply of {0} and {1} is {2}" .format(m, n, result))
Output:
nter a number 20 Enter another number 5 Multiply of 20 and 5 is 100
Using User Input (Command Line Arguments)
We can also accept input as command line arguments using sys.argv present inside sys module in python.
Then, we get product of two numbers using * operator in python as shown below –

Method 1
import sys a, b = sys.argv[1:3] print("Multiply is", float(a) * float(b))
Output:
Multiply is 30.0
Run above program with command line arguments as 10 and 3.
a, b = sys.argv[1:3] reads two values from command line and stores them in variable a and b.

Method 2
If two don’t want to apply restriction on how many numbers are to be read from command line, we can omit second argument in sys.argv as shown below –
import sys a, b = sys.argv[1:] print("Multiply is", int(a) * float(b))
Output:
Multiply is 30.0
Run with argument as 10 and 3.
Using Lambda
Using lambda and multiplication operator, we can multiply two numbers in python as shown below –
if __name__ == "__main__" : n1 = 12 n2 = 2 # Multiply two numbers multiplyNum = lambda n1, n2 : n1 * n2 print("Multiply =", multiplyNum(n1, n2))
Output:
Multiply = 24
Using Function
We can also write a function that returns product of two numbers in python as shown below –
def multiply(m, n): return m * n print("Multiply =", multiply(12, 2))
Output:
Multiply = 24
That’s how we can write python program to multiply two numbers with examples.
