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:

To write a factorial program in Python, you can define a function that uses recursion or iteration to calculate the factorial of a number. Here is an example using recursion: def factorial(n): if n == 0: return 1 else: return n * factorial(n-1)
