Output: 1) Enter a number to determine factorial Print ('The factorial of the number is ', factorial(factorialIP)) Python code: print('Enter a number for the purpose of determining factorial') In the given code, the loop begins with one, and then it multiplies by each number that precedes the actual number whose factorial is to be determined, and the function also checks for negative numbers.

In previous python code, the check for negative numbers was not applied, making the factorial function incomplete and prone to deliver an error message if negative numbers are put as an input. Let us take up the following python code that takes positive integers as input to determine the factorial of positive integers. The following python code illustrates the factorial function using function. Factorial of a Number using IF…else Statement When j is 2, the factor is multiplied with 2, and it will do the action till j comes at 4 to arrive at 24.

In this program, the factor is 1 when j is equal to 1. The above python program takes the input of positive numbers only, and it does not have a check of negative numbers in it. Print ('The factorial of the number is “, ffactor23) The following python code illustrates the factorial function using a loop.

In the following code, the loop begins with one, and then it multiplies by each number that precedes the actual number whose factorial is to be determined. Let us take up the example of python code that takes a positive integer as input to determine the factorial of positive integers. In this article, you’ll learn how to find the factorial of a number using different methods like…
