A factorial program in Python using recursion calculates the factorial of a number by breaking the problem into smaller subproblems. To determine the factorial , it makes use of a function that calls itself. This article covers several ways to find the factorial of a number in Python with examples, ranging from traditional iterative techniques to more concise recursive implementations and the utilization of built-in library functions. Python Program to Find Factorial of a Number Factorial of a number can be calculated in various ways. These include using a for loop, a recursive function, or a while loop. Each method has its advantages, and this tutorial covers all three approaches along with additional cases. Factorial is commonly used in mathematical computations, such as permutations, combinations, and series expansions.
