Python 提供了一种称为集合的数据类型，其元素必须是唯一的。它可用于执行不同的集合操作，如并集、交集、差集和对称差集。
源代码
# Program to perform different set operations like in mathematics
# define three sets
E = {0, 2, 4, 6, 8};
N = {1, 2, 3, 4, 5};
# set union
print("Union of E and N is",E | N)
# set intersection
print("Intersection of E and N is",E & N)
# set difference
print("Difference of E and N is",E - N)
# set symmetric difference
print("Symmetric difference of E and N is",E ^ N)
输出
Union of E and N is {0, 1, 2, 3, 4, 5, 6, 8}
Intersection of E and N is {2, 4}
Difference of E and N is {8, 0, 6}
Symmetric difference of E and N is {0, 1, 3, 5, 6, 8}
在这个程序中，我们取两个不同的集合，并对它们执行不同的集合操作。这也可以通过使用集合方法来完成。
