一.基本數(shù)據(jù)類(lèi)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 （元素的集合）
列表用[]
元祖：tuple
元祖用（）
字典：dict
注：所有的數(shù)據(jù)類(lèi)型都存在想對(duì)應(yīng)的類(lèi)列里

二.列表所有數(shù)據(jù)類(lèi)型：

基本操作：

• 索引
• 切片
• 追加
• 刪除
• 長(zhǎng)度
• 切片
• 循環(huán)
• 包含

三.所有列表數(shù)據(jù)類(lèi)型舉例

#!/usr/bin/env python
# -*- coding:utf-8 -*-

#append追加
name_list = ["zhangyanlin","suoning","nick"]
name_list.append('zhang')
print(name_list)

#count制定字符出現(xiàn)幾次
name_list = ["zhangyanlin","suoning","nick"]
name_list.append('zhang')
name_list.append('zhang')
name_list.append('zhang')
print(name_list.count('zhang'))

#extend可擴(kuò)展，批量往里加數(shù)據(jù)
name_list = ["zhangyanlin","suoning","nick"]
name = ["aylin","zhang","yan","lin"]
name_list.extend(name)
print(name_list)

#index找到字符所在的位置
name_list = ["zhangyanlin","suoning","nick"]
print(name_list.index('nick'))

#insert插入，往索引里面插入值
name_list = ["zhangyanlin","suoning","nick"]
name_list.insert(1,"zhang")
print(name_list)

#pop在原列表中移除掉最后一個(gè)元素，并賦值給另一個(gè)變量

name = name_list.pop()
print(name)

#remove移除,只移除從左邊找到的第一個(gè)

name_list.remove('nick')
print(name_list)

#reverse反轉(zhuǎn)
name_list = ["zhangyanlin","suoning","nick"]
name_list.reverse()
print(name_list)

#del刪除其中元素,刪除1到3之間的
name_list = ["zhangyanlin","suoning","nick"]
del name_list[1:3]
print(name_list)

四.索引

name_list = ["zhangyanlin","suoning""aylin""nick"]
print(name_list[0])

五.切片

name_list = ["zhangyanlin","suoning""aylin""nick"]
print(name_list[0:2])

六.總長(zhǎng)度len

name_list = ["zhangyanlin","suoning""aylin""nick"]
print(name_list[1:len(name_list)])
