How to check for at least TWO common members on two lists in python?

Question

I have the code that checks for at least one common item:

def common_members(list1, list2):
    for items1 in list1:
        for items2 in list2:
            if items1 == items2:

    return False

How do I revise this code such that it checks for TWO common items in two lists?

Answer 1

You can use sets to check how many items from several lists intersect:

len(set(items1).intersection(items2)) >= 2
