从两个列表中查找不同的组合

# 定义两个列表
list1 = [1, 2, 3, 4, 5]
list2 = [4, 5, 6, 7, 8]

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

# 找出只在list1中存在的元素
difference_in_list1 = set1 - set2
print("Elements only in list1:", difference_in_list1)

# 找出只在list2中存在的元素
difference_in_list2 = set2 - set1
print("Elements only in list2:", difference_in_list2)

# 找出两个列表中都不存在的元素（对称差集）
symmetric_difference = set1 ^ set2
print("Symmetric difference:", symmetric_difference)

# 保持原始顺序的差异查找
difference_in_list1_ordered = [item for item in list1 if item not in list2]
difference_in_list2_ordered = [item for item in list2 if item not in list1]
