Python中列表中的枚举项集

我需要创建许多数字集。我将我的输出和我需要的输出相加。 我编写了列表的第一个项目输出，然后我需要对所有项目使用相同的输出

a = [1, 2, 3, 4, 5, 6, 7, 8]
for index, item in enumerate(a):
    index_0 = index
    index_1 = index + 1
    index_2 = index + 2
    index_3 = index + 3
    print((a[index_0], a[index_1], a[index_2], a[index_3]))
>>>
1, 2, 3, 4
2, 3, 4, 5
3, 4, 5, 6
4, 5, 6, 7
5, 6, 7, 8

我在为每一项寻找什么：

1,2,3,4
1,2,3,5
1,2,3,6
1,2,3,7
1,2,3,8
1,2,4,5
1,2,4,6
1,2,4,7
1,2,4,8
1,2,5,6
1,2,5,7
1,2,5,8
1,2,6,7
1,2,6,8
1,2,7,8
1,3,4,5
1,3,4,6
1,3,4,7
1,3,4,8
1,3,5,6
1,3,5,7
1,3,5,8
1,3,6,7
1,3,6,8
1,3,7,8
1,4,5,6
1,4,5,7
1,4,5,8
1,4,6,7
1,4,6,8
1,4,7,8
1,5,6,7
1,5,7,8
1,6,7,8

您是否希望使用itertools组合：

输出：

你们是在寻找一个数字的每四个长度的组合吗？如果不是的话，那么你的问题必须更具描述性。我还希望您认识到set在Python中是一个保留字，您的代码没有使用这种类型的东西，这让人们感到不舒服。是的！谢谢如果我想在数字之间加一个限制，例如，最大10个微分值，比如：1,2,3,4，最大值是1,2,3,10，下一个是1,2,4,5，最大值是1,2,4,10。。。怎么做？
