字典

一.定义

1、语法

name_1 = [1,2,3,4,5,6,7,10]
#把列表转换集合
print(name_1,type(name_1))
#[1, 2, 3, 4, 5, 6, 7, 10] <class 'list'>

 

 

 

 

 二.关系测试

#1.交集(intersection)
name_1 = [1,2,3,4,5,6,7,10]
name_2 = [1,3,4,7,10]
name_1 = set(name_1)
name_2 = set(name_2)
#输出结果
print( name_1.intersection(name_2))

#2.并集intersection
name_1 = [1,2,3,4,5,6,7,10]
name_2 = [1,3,4,7,10]
name_1 = set(name_1)
name_2 = set(name_2)
print(name_1.intersection(name_2))
