爲什麼這個階乘函數會給出錯誤的結果？

Question

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

結果第一5號是：

1 - > 1

2 - > 2

3 - > 6

4 - > 42

5 - > 1806

我的功能有什麼不正確？

Answer 1

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

更換

result = result * (result+1) 

與

result = result * (i + 1)
