我需要通过列表计数

Question

我有多个列表和一个大列表，我想检查大列表是否有我的一些小列表和计数，但我不想要冗余，例如：

list1 = [ "A" , "B" , "C" , "D"]

List2 = ['K' , "l" , "M"]

main_lists = [["A","C","K","L"] , ["B" , "C" , "M"]]

count1 = 0

count2 = 0

如果我在两个列表中的主列表中找到任何项目，我需要继续，我增加一个计数器但不是多余的，所以我的这种情况的输出应该是 count 1 = 2 count 2 = 2

我的列表中的A和C并不重要，只有其中1个会增加计数，我该怎么办

Answer 1

IIUC，您可以执行以下操作：list1 = ["A", "B", "C", "D"]list2 = ['K', "l", "M"]main_lists = [["A", "C", "K", "L"], ["B", "C", "M"]]set1 = set(list1)set2 = set(list2)count1 = sum(any(ie in set1 for ie in e) for e in main_lists)count2 = sum(any(ie in set2 for ie in e) for e in main_lists)print(count1)print(count2)
