递归求阶乘

def factorial(n):
    result = n
    for i in range(1,  n):
        result *= i
    return result
number = int(input("请输入一个正整数："))

result = factorial(number)
print("%d的阶乘是：%d" %(number, result))

def factorial(n):
    if n == 1:
        return 1
    else:
        return n* factorial(n - 1)
number = int(input("请输入一个正整数："))

result = factorial(number)
print("%d的阶乘是：%d" %(number, result))
