python中比较四个列表的一种更简单的方法

list1 = [1, 2, 3, 4]
list2 = [3, 4, 5, 6]
list3 = [5, 6, 7, 8]
list4 = [7, 8, 9, 10]

# 将列表转换为集合
set1 = set(list1)
set2 = set(list2)
set3 = set(list3)
set4 = set(list4)

# 求交集
intersection = set1 & set2 & set3 & set4

# 求并集
union = set1 | set2 | set3 | set4

# 求差集
difference = set1 - set2 - set3 - set4

# 打印结果
print("交集:", intersection)
print("并集:", union)
print("差集:", difference)

交集: set()
并集: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
差集: {1, 2}
