? 列表简介:
o 列表是序列对象,可包含任意的Python数据信息,如字符串、数字、列表、元组等
o 列表的数据是可变的,我们可通过对象方法对列表中的数据进行增加、修改、删除等操作
o 可以通过list(seq)函数把一个序列类型转换成一个列表
1.append(x),在列表尾部追加单个对象x,使用多个参数会引起异常
append(self, p_object)
1. |
>>>lst=[1,2,3] >>>relust=lst.append(4) >>>print result [1,2,3,4] |
2.count(x),返回对象x在列表中出现的次数
3.extend(L),将列表L中的表项添加到列表中,返回None
4.Index(x),返回列表中匹配对象x的第一个列表项的索引,无匹配元素时产生异常
5.insert(i,x),在索引为i的元素前插入对象x,如list.insert(0,x)在第一项前插入对象,返回None
6.pop(x),删除列表中索引为x的表项,并返回该表项的值,若未指定索引,pop返回列表最后一项
7.remove(x),删除列表中匹配对象x的第一个元素,匹配元素时产生异常,返回None
8.reverse(),颠倒列表元素的顺序
9.sort(),对列表排序,返回none,bisect模块可用于排序列表项的添加和删除
