为方便以后的学习查找，记载下来，嘻嘻。。

首先保证python已安装redis

python -m pip install redis

redis共享数据步骤：

1. 导入redis库

2. 定义connection参数，包括server IP, redis端口号 ，redis passward

3. 示例化redis connection对象

4. 使用connection obj向redis server上传message

5. 使用connection obj从redis server拉取message

redis使用示例：

# step 1: import the redis-py client package
    import redis
    
    # step 2: define our connection information for Redis
    # Replaces with your configuration information
    redis_host = "localhost"  #redis_host should be the server IP
    redis_port = 6379
    redis_password = ""
    
    
    def hello_redis():
        """Example Hello Redis Program"""
        
        # step 3: create the Redis Connection object
        try:
        
            # The decode_repsonses flag here directs the client to convert the responses from Redis into Python strings
            # using the default encoding utf-8.  This is client specific.
            r = redis.StrictRedis(host=redis_host, port=redis_port, password=redis_password, decode_responses=True)
        
            # step 4: Set the hello message in Redis 
            r.set("msg:hello", "Hello Redis!!!")
    
            # step 5: Retrieve the hello message from Redis
            msg = r.get("msg:hello")
            print(msg)        
        
        except Exception as e:
            print(e)
    
    
    if __name__ == '__main__':
        hello_redis()

python redis很好用有木有！！超赞！
