def factorial(n): if n < 0: raise ValueError("阶乘未定义负数") result = 1 for i in range(2, n + 1): result *= i return result1. 问题要求编写一个计算数字阶乘的Python函数。2. 阶乘定义:n! = 1×2×3×...×n,其中0! = 1,负数没有阶乘。3. 函数首先

Python def fact_loop(num): if num < 0: return 0 if num == 0: return 1 factorial = 1 for i in range(1, num + 1): factorial = factorial * i return factorial You can also use a recursive function to find the factorial. This is more complicated but also more elegant than using...
