分别有两个集合{1,2,1,3,4,5,6,7}，{1,2,3,8,9,7,10}，求两个集合的差集、并集、交集

以下是两个集合的差集、并集和交集的演示：

1. 差集：

set1 = {1, 2, 1, 3, 4, 5, 6, 7}
set2 = {1, 2, 3, 8, 9, 7, 10}

difference = set1 - set2
print("差集：", difference)  # 输出：{4, 5, 6}

2. 并集：

set1 = {1, 2, 1, 3, 4, 5, 6, 7}
set2 = {1, 2, 3, 8, 9, 7, 10}

union = set1 | set2
print("并集：", union)  # 输出：{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

3. 交集：

set1 = {1, 2, 1, 3, 4, 5, 6, 7}
set2 = {1, 2, 3, 8, 9, 7, 10}

intersection = set1 & set2
print("交集：", intersection)  # 输出：{1, 2, 3, 7}
