Python操作Redis的5种数据类型

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S2  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)) 9    10   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)7 8 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)6 7 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) 8  9 10  结果: [one, two, three, four, five]
