GETkey获取某个key 的value值。如key不存在,则返回字符串“nil”;如key的值不为字符串类型,则返回一个错误。 GETSETkey value可以理解成获得的key的值然后SET这个值,更加方便的操作 (SET bruce 10 paitoubing,这个时候需要修改bruce变成1234567890并获取这个以前的数据paitoubing,GETSET bruce 10 1234567890) ...

To get the item in a specific index, we use the “LINDEX” command. The first argument is the key and the second argument is the index number. Note that lists are zero-indexed, which means that the index starts at 0.要获取特定索引中的项目,我们使用“LINDEX”命令。第一个参数是键,第二...
