Posted 2020-09-11

1.安装redis

2.连接redis

import redis
redis_client = redis.Redis("192.168.86.127", port=6379, db=10)

3.在indexs对应的list中添加10条数据

for i in range(10):
    redis_client.rpush("indexs",i)

4.查看indexs键中长度

llen = redis_client.llen("indexs")
print ‘llen:‘,llen

5.从redis某一键中移除一条数据

job = redis_client.lpop("indexs")
print ‘job:‘,job

6.获取indexs键中所有数据

jobs = redis_client.lrange(‘indexs‘,0,-1)

7.redis设置值

redis_client.hmset("hot_keys",{"singers":"hot_singer"})
redis_client.hmset("hot_keys",{"songs":"hot_song"})

8.redis获取值

arraykey=["singers","songs"]
for key in arraykey:
    for line in  redis_client.hmget("hot_keys",key):
        print key,line

9.redis获取某一db下所有keys

 print redis_client.keys()

10.redis删除某一key

redis_client.delete(‘indexs‘)
