我想用如下词典：

示例：{[8，16]：[[1,2,4,8]，8]，[16，24]：[[1,2,3,4,8,12]，12]}

8和16是将要输入的两个数字，我需要构造一个如上所述的字典。在

使用setdefault，我可以为dictionary中的值创建一个列表，但不能为键创建一个列表

以下是我的代码：#!/usr/bin/env python

"""

This Program calculates common factors between two Numbers , which

is stored on a list and also greatest common factor is also computed.

All this is stored in a dictionary

Example: { '[n1, n2]': [[Commonfac1(n1,n2), Commonfac2(n1,n2)....Commonfacn(n1,n2)],GreatestCommonFactor] }

"""

def Factors(number):

result = []

for i in range(1, number+1):

if (number % i) == 0:

result.append(i)

return result

def Common_Factors(n1, n2):

result = []

for element in n1:
