1.连接redis(两种方式)
1 # decode_responses=True: 解决获取的值类型是bytes字节问题
2 r = redis.Redis(host=‘localhost‘, port=‘6379‘, db=0, decode_responses=True)
1 pool = redis.ConnectionPool(host=‘localhost‘, port=6379, db=0, decode_responses=True)
2 r = redis.Redis(connection_pool=pool)
2.字符串类型 String
1 # ex过期时间 单位秒S
2 r.set(‘name‘, ‘Jack‘, ex=20)
3 rst = r.get(‘name‘)
4 print(rst)
5
6
7 结果: "Jack"
3.列表类型 list
1 r.lpush(‘object‘, ‘one‘)
2 r.lpush(‘object‘, ‘two‘)
3 r.lpush(‘object‘, ‘three‘)
4 r.lpush(‘object‘, ‘four‘)
5 r.lpush(‘object‘, ‘five‘)
6 r.lpush(‘object‘, ‘six‘)
7 ret = r.lrange(‘object‘, 0, 5)
8 print(ret[::-1], len(ret))

11 结果: [‘one‘, ‘two‘, ‘three‘, ‘four‘, ‘five‘, ‘six‘] 6
4.哈希类型 hash
1 r.hset(‘user:info‘, ‘name‘, ‘Jack‘)
2 r.hset(‘user:info‘, ‘age‘, 20)
3 r.hset(‘user:info‘, ‘phone‘, ‘18712909999‘)
4 r.hset(‘user:info‘, ‘email‘, ‘123@gmail.com‘)
5 rst = r.hgetall(‘user:info‘)
6 print(rst)

9 结果: {‘age‘: ‘20‘, ‘email‘: ‘123@gmail.com‘, ‘name‘: ‘Jack‘, ‘phone‘: ‘18712909999‘}
5.集合类型 set
1 r.sadd(‘set‘, ‘one‘)
2 r.sadd(‘set‘, ‘two‘)
3 r.sadd(‘set‘, ‘three‘)
4 res = r.smembers(‘set‘)
5 print(res)

8 结果: {‘two‘, ‘one‘, ‘three‘}
6.有序集合类型 sorted set
1 r.zadd(‘mark‘, ‘one‘, 1)
2 r.zadd(‘mark‘, ‘two‘, 2)
3 r.zadd(‘mark‘, ‘three‘, 3)
4 r.zadd(‘mark‘, ‘four‘, 4)
5 r.zadd(‘mark‘, ‘five‘, 5)
6 result = r.zrange(‘mark‘, 0, 10)
7 print(result)
