tuple

 #tuple比list好的地方
 #1.性能优化（immutable会作为常量在编译时确定）（immutable--不可变）
 #2.线程安全
 #3.可以作为dict的key
 #4.可拆包
 #tuple 拆包
 user_tuple1 = ('ray',27,170)
 name,age,height = user_tuple1
 print(name,age,height)
 user_tuple2 = ('ray',27,170,'shiyan','college')
 name,*other = user_tuple2
 print(name,other)
 #tuple不可变性不是绝对的
 user_tuple3 = ('ray',[27,'shiyan'])
 print(user_tuple3)
 user_tuple3[1].append('college')
 print(user_tuple3)
 user_dict = {}
 user_dict[user_tuple1] = 'ray'

set

 #list 转 set
 list_1 = [1,3,5,7,9,11,13]
 list_1 = set(list_1)
 list_2 = {3,7,9,11,2,4,6}
 #交集
 print(list_1.intersection(list_2))

 #并集
 print(list_1.union(list_2))
 print(list_1 | list_2)
 #差集
 print(list_1.difference(list_2))
 print(list_1 - list_2)
 #子集/父集
 print(list_1.issubset(list_2))
 print(list_1.issuperset(list_2))
 #对称差集(两个集合中互相不存在的）
 print(list_1.symmetric_difference(list_2))
 print(list_1 ^ list_2)
 #添加

string

str1 = 'good good study,day day up'
print(str1.capitalize())  # 首字母大写
print(str1.center(50,'-'))
list1 = ['1','2','3']
print('+'.join(list1))
