Python操作Redis数据库

import redis

cf.read("conf.conf")

cf = configparser.ConfigParser()

class Redis_Operation:
    def __init__(self, host=cf.get("redis_address", "redis_host"), 
        port=cf.getint("redis_address", "redis_port"),
        db=cf.getint("redis_address", "db"), password=cf.get("redis_address", 
        "password")):
        self.r = redis.Redis(host=host, port=port, db=db, password=password)
    
    def insert_hash_data(self, key, second_key, data):
        self.r.hset(key, second_key, data)
        self.r.save()
        return 1
 
    def get_hash_data(self, key,  second_key):
        res = self.r.hget(key, second_key)
        return res    

    def del_hash_data(self, key, second_key):
        self.r.hdel(key, second_key)
        return 1

    def query_hash_keys(self, key):
        res = self.r.hkeys(key)
        return res
            
    def insert_into_train_queue(self, model_name):
        res = self.r.rpush("train_queue", model_name)
        return 1

    def pop_train_queue(self):
        res = self.r.lpop("train_queue")
        return res
    
    def get_data_by_index(self, index):
        res = self.r.lindex("train_queue", index) 
        return res

cf.get()函数是从配置文件中读取信息，如果使用的redis没有密码就把password=password这个字段去掉就好。每个函数的作用如同函数名一样，导入类之后直接调用就行。
