Apr 8, 2025 · In Python, we can calculate the factorial of a number using various methods, such as loops, recursion, built-in functions, and other approaches. Example: Simple Python program to find the factorial of a number

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 input 5 , the output should be 120

Jan 6, 2022 · How do I go about computing a factorial of an integer in Python? The easiest way is to use math.factorial (available in Python 2.6 and above): If you want/have to write it yourself, you can use an iterative approach: fact = 1. for num in range(2, n + 1): fact *= num. return fact. or a recursive approach: if n < 2: return 1. else:
