一.基本數(shù)據(jù)類型
　　整數(shù)：int
　　字符串：str(注：\t等于一個(gè)tab鍵)
　　布爾值： bool
　　列表：list?
　　列表用[]
　　元祖：tuple
　　元祖用（）
　　字典：dict
注：所有的數(shù)據(jù)類型都存在想對(duì)應(yīng)的類列里，元祖和列表功能一樣，列表可以修改，元祖不能修改。

二.列表所有數(shù)據(jù)類型：

基本操作：

• 索引
• 切片
• 長(zhǎng)度
• 包含
• 循環(huán)

class tuple(object):"""tuple() -> empty tupletuple(iterable) -> tuple initialized from iterable's itemsIf the argument is a tuple, the return value is the same object."""def count(self, value): # real signature unknown; restored from __doc__""" T.count(value) -> integer -- return number of occurrences of value """（T.count(價(jià)值)- >整數(shù),返回值的出現(xiàn)次數(shù)）return 0def index(self, value, start=None, stop=None): # real signature unknown; restored from __doc__"""T.index(value, [start, [stop]]) -> integer -- return first index of value.Raises ValueError if the value is not present."""（T。指數(shù)(價(jià)值,[開始,[不要]])- >整數(shù),返回第一索引值。提出了ValueError如果不存在的價(jià)值。）return 0def __add__(self, *args, **kwargs): # real signature unknown""" Return self+value.

三.所有元祖數(shù)據(jù)類型舉例

#count 用于計(jì)算元素出現(xiàn)的個(gè)數(shù) name_tuple = ("zhangyanlin","suoning","nick") print(name_tuple.count('zhangyanlin'))#index獲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減1的元素 name_tuple = ("zhangyanlin","suoning","nick") print(name_tuple[0:len(name_tuple)-1])

六.總長(zhǎng)度len

#取出最后一位減1的元素 name_tuple = ("zhangyanlin","suoning","nick") print(name_tuple[len(name_tuple)-1])

七.for循環(huán)

name_tuple = ("zhangyanlin","suoning","nick") for i in name_tuple:print(i)
