12/19/2023 0 Comments Factorial pythonLook at the program to understand the implementation of the above-mentioned approach. Step 5 - Print the result Python Program 1 Step 4 - Return the value of the number multiplied by the factorial of the number minus 1 Step 3 - If false, call the function recursively to calculate factorial of the number minus 1 Step 2 - Check if the entered number is 1 or 0, if true return the number Step 1 - Define function factorial() to calculate factorial Follow the algorithm to understand the working process better. We will define a recursive function for finding the factorial of a number given by the user. Let us look at these approaches individually, Program 1: using recursionĪs discussed earlier in this tutorial, recursion is a process in which the function calls itself directly or indirectly in a program. There are three different approaches to execute this task in Python: The program should take input as follows and return the factorial of that number. ![]() Factorial of a negative number is not defined and the factorial of 0 is always 1.įor example, Factorial of 7 is: 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5040 Formula The factorial of a non-negative number is the product of all the integers from 1 to that number. In this tutorial, we will learn how to find the factorial of a number and display it.
