To find the factorial, fact() function is written in the program. This function will take number (num) as an argument and return the factorial of the number.# function to calculate the factorial def fact(n): if n == 0: return 1 return n * fact(n - 1) # Main code num = 4 #...
Write a function to calculate the factorial of a number. The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. For example, for input5, the output should be 120 1 2 def factorial(n): Check Code Share on: Did you find this...
In this tutorial, we will learn how to find the factorial of a given number using Python program?
(1) Go topythontutor.comand select a language. Here the user chose Java and wrote code to recursively create aLinkedList. (2) Press ‘Visualize’ to run the code. This code ran for 46 steps, where each step is one executed line of code. Go to any step (2a) and see what line of...
