我设法对两个lists进行了所有可能的组合，但是直到list1中的值超过另一个为止，我一直不知道如何创建组合。
list1 = [10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,90,100]
list2 = [30,35,40,45,50,55,60,65,70,75,80,85,90,95,100,105,110,115,120,125,130,135,
140,150,155,160,165,170,
175,180,185,195,200]
我尝试过并且仍在修改的代码，在此处搜索了stackoverflow：combination of two lists
y = [zip(x,list1) for x in itertools.permutations(list2,len(list1)) if x > list1]
预期输出：
combi = [[(30,10),(30,15),(30,20),(30,25)],[(35,10),......,
(35,30)],.....,[(120,10),.......,(120,100)......]]
如果有一种方法可以很好地限制组合起来的第一项和第二项之间的差异。
谢谢
答案 0 :(得分：2)
您无需为此使用itertools或zip。您可以通过列表理解中的两个for循环来实现：
result = [[(elem2,elem1) for elem1 in list1 if elem1 < elem2] for elem2 in list2]
答案 1 :(得分：1)
您可以使用嵌套列表理解：
[[(a, b) for b in list1 if b < a] for a in list2]
这将返回：
