Where n is any positive integer 3) Calculate factorial using Python math. Python math library contains a factorial() function which calculates the factorial of the input value and returns its output value. There are several important ways to compute factorials in Python For better or worse, there’s not one single way to compute factorials in Python or in Numpy. #Increase the value of value of `i` on every iterationįactorial: 479001600 Calculate Factorial using Python factorial() function #Factoral can't be find of negative numberįactorial : 3628800 2) Python Program to calculate Factorial using a while loop #Python program to find factorial of a number using While Loop 1) Python Program to calculate Factorial using for loop: #Python program to find factorial of a number using for loop ![]() In this tutorial, you will learn how to write a python program to find factorial of any non-negative integer which is greater than 0. There is no factorial defined for negative numbers whereas factorial of 0! is 1. ![]() Note: Factorial is represented by exclamatory mark (!). Below we define a function called factorial() which computes the factorial of an. Factorial of a number is denoted by n is the product of all positive integers less than or equal to n: So what is 10 To find 5 Since 0 is not a positive. ![]() ![]() Factorial of any positive number (n) is a product of all number which is less than or equal to (n) but greater than 0. We can also use a recursive function to compute the factorial of a number.
