Python并集是什么意思？
本文教程操作环境：windows7系统、Python 3.9.1，DELL G3电脑。
以属于A或属于B的元素为元素的集合成为A与B的并集。
1、概念
并集就是取所有集合的所有元素，如果出现重复的保留一个。使用符号 | 或者 union 方法完成。
2、实例
my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}
both=my_set1|my_set2
print(both)
使用union完成。
my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}
both=my_set1.union(my_set2)
print(both)
my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}
both=my_set1|my_set2
print(both)
使用union完成。
my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}
both=my_set1.union(my_set2)
print(both)
my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}
both=my_set1|my_set2
print(both)
使用union完成。
my_set1={"apple","orange","pear","banana","food"}
my_set2={"apple","orange","pear"}
both=my_set1.union(my_set2)
print(both)
