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 （元素的集合）
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
二.列表所有数据类型：
基本操作：
•索引
•切片
•追加
•删除
•长度
•切片
•循环
•包含

三.所有列表数据类型举例
#!/usr/bin/env python
# -*- coding:utf-8 -*-
#append追加
name_list = ["zhangyanlin","suoning","nick"]
name_list.append('zhang')
print(name_list)
#count制定字符出现几次
name_list = ["zhangyanlin","nick"]
name_list.append('zhang')
name_list.append('zhang')
name_list.append('zhang')
print(name_list.count('zhang'))
#extend可扩展，批量往里加数据
name_list = ["zhangyanlin","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","nick"]
print(name_list.index('nick'))
#insert插入，往索引里面插入值
name_list = ["zhangyanlin","nick"]
name_list.insert(1,"zhang")
print(name_list)
#pop在原列表中移除掉最后一个元素，并赋值给另一个变量
name_list = ["zhangyanlin","nick"]
name = name_list.pop()
print(name)
#remove移除,只移除从左边找到的第一个
name_list = ["zhangyanlin","nick"]
name_list.remove('nick')
print(name_list)
#reverse反转
name_list = ["zhangyanlin","nick"]
name_list.reverse()
print(name_list)
#del删除其中元素,删除1到3之间的
name_list = ["zhangyanlin","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.总长度len
name_list = ["zhangyanlin","suoning""aylin""nick"] print(name_list[1:len(name_list)])
七.for循环
name_list = ["zhangyanlin","suoning""aylin""nick"] for i in name_list: print(i)
以上就是小编为大家带来的深入了解Python数据类型之列表全部内容了，希望大家多多支持编程小技巧~
