Python Function With No Parameter, No Return

In the last article, we have seen how a user-defined function is created. The user-defined function has two parts – the function definition and the function call.The function definition may or may not have parameters and it may or may not return a value.

In this article, you will see an example of python function with no parameters, and no return.

Program to Compute Factorial of a Number

This program is a simple program that computes factorial of a given input number.

## Program To Compute Factorial of a Number

## Function Definition

def factorial_number():
    
     factorial = 1
     fact_number = int(input("Enter a Number to Get its Factorial: "))
     for i in range(1, fact_number + 1):
        factorial = factorial * i
     print("The factorial is" , factorial)

## Function Call
factorial_number()

The above program does not take any parameters and does not return anything. The output of the program is given below.

========= RESTART: C:/Python_projects/Functions/Factorial.py =============
Enter a Number to Get its Factorial: 5
The factorial is 120
