redis学习(六)——Sorted Set数据类型
一、概述:Sorted Set(有序集合)和Set类型极为相似,它们都是字符串的集合,都不允许重复的成员出现在一个Set中。它们之间的主要差别是Sorted Set中的每一个成员都会有一个分数(score)与之关联,Redis正是通过分数来为集合中的成员进行从小到大的排序。然而需要额外指出的是,尽管...

Python 列表排序方法reverse、sort、sorted操作方法
python语言中的列表排序方法有三个:reverse反转/倒序排序、sort正序排序、sorted可以获取排序后的列表。在更高级列表排序中,后两中方法还可以加入条件参数进行排序。reverse()方法将列表中元素反转排序,比如下面这样>>> x = [1,5,2,3,4]>...

redis数据类型:sorted sets类型及操作
sorted sets类型及操作:sorted set是set的一个升级版本,它是在set的基础上增加了一个顺序属性,这一属性在添加修改元素的时候可以指定,每次指定后,zset会自动重新按新的值调整顺序。可以理解为两列的mysql表,一列存value,一列存顺序。操作中key理解为zset的名字。z...
