一.基本数据类型
整数：int
字符串：str(注：\t等于一个tab键)
布尔值： bool
列表：list
列表用[]
元祖：tuple
元祖用（）
字典：dict
注：所有的数据类型都存在想对应的类列里，元祖和列表功能一样，列表可以修改，元祖不能修改。
二.列表所有数据类型：
基本操作：
- 索引
- 切片
- 长度
- 包含
- 循环

三.所有元祖数据类型举例
#count 用于计算元素出现的个数
name_tuple = ("zhangyanlin","suoning","nick")
print(name_tuple.count('zhangyanlin'))#index获取指定元素的指定位置
name_tuple = ("zhangyanlin","suoning","nick")
print(name_tuple.index('zhangyanlin'))
四.索引
name_tuple = ("zhangyanlin","suoning","nick")
print(name_tuple[1])
五.切片
#取出第一位到最后一位减1的元素
name_tuple = ("zhangyanlin","suoning","nick")
print(name_tuple[0:len(name_tuple)-1])
六.总长度len
#取出最后一位减1的元素
name_tuple = ("zhangyanlin","suoning","nick")
print(name_tuple[len(name_tuple)-1])
七.for循环
name_tuple = ("zhangyanlin","suoning","nick")
for i in name_tuple:print(i)
