本教程的操作环境：windows7系统，Python 3.9.1，DELL G3电脑。

以属于A和B的元素为元素的集合成为A和B的交集。

1、概念

交集就是要求两个共同的元素集合。

my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}
both=my_set1&my_set2
print(both)

2、实例

除了通过 & 除符号外，还可以集合 intersection 方法完成。

my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}

both=my_set1.intersection(my_set2)
print(both)

以上是Python交集的作用介绍，希望对大家有所帮助。更多Python学习指导：python基础教程
