可以将具有重复值的列表转换为python中的多集吗？

问题描述

我有两个包含重复值的列表，我想将重复值与在任一列表中仅出现一次的值相交。 我只是一个初学者，很想听听简单的建议！

解决方法

方法1

Uncaught Error: Expected element to be passed to render iframe

方法2

l1=[1,2,3,4]
l2=[1,5]
intersection=[value for value in l1 if value in l2]
for x in l1+l2:
    if x not in intersection: 
        intersection.append(x)
print(intersection)
