Write A Python Program To Find Factorial Of A Number Using Recursion

Write A Python Program To Find Factorial Of A Number Using Recursion In this article, we are going to calculate the factorial of a number using recursion. examples: output: 120. input: 6. output: 720. implementation: if fact (5) is called, it will call fact (4), fact (3), fact (2) and fact (1). so it means keeps calling itself by reducing value by one till it reaches 1. Learn how to use recursion to calculate the factorial of a number in python. see the python code, explanation and example of the factorial function.

Python Program To Find Factorial Of Number Using Recursion # recursive case: n * factorial of (n 1) return n * factorial(n 1) def main (): try: # input the number . number = int (input ("enter a number: ")) # check for negative numbers if number < 0: print ("factorial cannot be calculated for negative numbers.") return # calculate factorial . result = factorial(number).
