What is Factorial Program? Factorial Program in C: Factorial of n is   the product of all positive descending integers . Factorial of n is denoted by n!. For example: 5! = 5*4*3*2*1 = 120. How do you code a factorial for a loop in Python? num = int(input("enter a number: ")) fac = 1. for i in range(1, num + 1): fac = fac * i. print("factorial of ", num, " is ", fac) Factorial Program in Python # Python program to find the factorial of a number provided by the user. # change the value for a different result num = 7 # To take input from the user #num = int(input("Enter a number: ")) factorial = 1 # check if the number is negative, positive or zero if num < 0 : print ( "Sorry, factorial does not exist for negative numbers" ) elif num == 0 : print ( "The factorial of 0 is 1" ) else : for i in range( 1 ,num + 1 ): factorial = factorial*i print ( "The factorial of" ,num, "is"

  Python   is a dynamic, high-level, free open source, and interpreted programming language. It supports object-oriented programming as well as procedural-oriented programming. In Python, we don’t need to declare the type of variable because it is a dynamically typed language. For example, x = 10 Here, x can be anything such as String, int, etc. Features in Python There are many features in Python, some of which are discussed below – 1.
