序列(sequence)

1. 可变序列
   1.1. 列表(list)

stus = [1,2,3]
stus[1:]
stus[:3]
stus[:]

2. 不可变序列
   2.1. 字符串(string)
   2.2. 元组(tuple)

my_tuple = (1,2,3,4,5)

集合(set)

s = {10,3,5,1,2,1,2,3,1,1,1,1}
s = set()
s = set([1,2,3,4,5,1,1,2,3,4,5])

s.add(10)

s.update(s2)

result = s.pop()

s.remove(100)

s.clear()

s.copy()

字典(dict)

d = {
'name':'孙悟空' , 
'age':18 , 
'gender':'男' , 
'name':'sunwukong'
}
