Python数据类型之元祖
一.基本数据类型
整数：int
字符串：str(注： 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

#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) |
