python操作Redis

使用redis模块，可以方便的使用脚本完成Redis数据构造和清理。本文借助脚本，给大家演示一下redis常用数据结构list、set、hash等数据结构的常用增删改查的操作。其他命令可以参考：

Redis 命令参考：http://doc.redisfans.com/

pip install redis

上代码：

class RedisOperate:
    def __init__(self, host='localhost', port=6379, db=0, password=None):

            for subkey, sub_value in self.rcon.hgetall(name).items():
                hash_res[subkey.decode()] = sub_value.decode()
        return hash_res
    def _insert_hash(self, hash_json=None):
