Factorial Python Program

Here's a small Python example that calculates the factorial of a given number using recursion def factorial(n): if n == 0: return 1 else: return n * factorial(n-1) # Example usage number = 5 result = factorial(number) print("The factorial of {number} is: ",result)

Description : In this example, the factorial function takes an integer 'n' as input and calculates its factorial recursively. The base case is when 'n' is equal to 0, in which case the function returns 1. Otherwise, it multiplies 'n' by the factorial of n-1. The example then demonstrates the usage of the factorial function by calculating the factorial of 5 and printing the result. When executed, the output will be: ('The factorial of {number} is: ', 120)
