如何检查一个列表是否包含另一个列表的两个元素？

def check_lists(list1, list2):
    for element in list2:
        if element not in list1:
            return False
    return True

list1 = [1, 2, 3, 4, 5]
list2 = [3, 4]
result = check_lists(list1, list2)
print(result)  # 输出 True

def check_lists(list1, list2):
    set1 = set(list1)
    set2 = set(list2)
    return set2.issubset(set1)

list1 = [1, 2, 3, 4, 5]
list2 = [3, 4]
result = check_lists(list1, list2)
print(result)  # 输出 True
