为什么这个阶乘函数给出了错误的结果？

Question

def Factorial(n):
   result = 1
   for i in range(1,n):
        result = result * (result+1)
   print(result)
Factorial(5)

前5个数字的结果是：

1 - ＆gt; 1

2 - ＆gt; 2

3 - ＆gt; 6

4 - ＆gt; 42

5 - ＆gt; 1806

我的功能有什么不正确？

Answer 1

def Factorial(n):
   result = 1
   for i in range(1,n):
        result = result * (i+1)
   print(result)

替换

result = result * (result+1)

与

result = result * (i + 1)
