python操作redis list

Pygo 63

前言:

而今姐妹们对“python redis list”可能比较注意,兄弟们都需要知道一些“python redis list”的相关内容。那么小编同时在网络上网罗了一些有关“python redis list””的相关知识,希望你们能喜欢,咱们快快来了解一下吧!

上一篇文章写了redis客户端对list的各种操作,这篇文章用python客户端来复现一下。(强烈建议结合上篇文章看,效果更佳)

from redis import Redisif __name__ == '__main__':    client = Redis(host='192.168.174.129', port=6666, decode_responses=True)    try:        # 左右插入        print(client.rpush('list1', 1, 'a', 2)) # 3        print(client.lpush('list1', 0, -1))# 5        # 还有 rpushx/lpushx  存在才push        print(client.lrange('list1', 0, -1))# ['-1', '0', '1', 'a', '2']        # before/after 插入        print(client.linsert('list1', 'before', 'a', 1.5)) # 6        print(client.lrange('list1', 0, -1)) # ['-1', '0', '1', '1.5', 'a', '2']        print(client.linsert('list1', 'after', 'a', 'b')) # 7        print(client.lrange('list1', 0, -1)) # ['-1', '0', '1', '1.5', 'a', 'b', '2']        # 测试列表里面有2个相同的value,在insert的时候,如何插入        print(client.rpush('list2', 1, 'a', 2, 'a', '3')) # 5        print(client.linsert('list2', 'before', 'a', 1.5)) # 6        print(client.lrange('list2', 0, -1)) # ['1', '1.5', 'a', '2', 'a', '3']        # lpop/rpop        print(client.lpop('list2')) # 1        print(client.rpop('list2')) # 3        client.rpush('list3', 1, 'a', 2, 'a', '3', 'a', 4, 'a', 5, 'a')        client.rpush('list4', 1, 'a', 2, 'a', '3', 'a', 4, 'a', 5, 'a')        client.rpush('list5', 1, 'a', 2, 'a', '3', 'a', 4, 'a', 5, 'a')        # lrem        print(client.lrem('list3', 2, 'a')) # 2        print(client.lrange('list3', 0, -1)) # ['1', '2', '3', 'a', '4', 'a', '5', 'a']        print(client.lrem('list4', -2, 'a')) # 2        print(client.lrange('list4', 0, -1)) # ['1', 'a', '2', 'a', '3', 'a', '4', '5']        print(client.lrem('list5', 0, 'a')) # 5        print(client.lrange('list5', 0, -1)) # ['1', '2', '3', '4', '5']        # ltrim        print(client.ltrim('list5', 2, 4)) # True        print(client.lrange('list5', 0, -1)) # ['3', '4', '5']        # lindex        print(client.lindex('list5', -1)) # 5        print(client.lindex('list5', -3)) # 3        print(client.lindex('list5', -0)) # 3        # llen        print(client.llen('list5')) # 3        # lset        print(client.lset('list5', 2, 33)) # True        print(client.lrange('list5', 0, -1)) # ['3', '4', '33']        # rpoplpush        print(client.lrange('list4', 0, -1)) # ['1', 'a', '2', 'a', '3', 'a', '4', '5']        print(client.rpoplpush('list4', 'list5')) # 5        print(client.lrange('list4', 0, -1)) # ['1', 'a', '2', 'a', '3', 'a', '4']        print(client.lrange('list5', 0, -1)) # ['5', '3', '4', '33']        print(client.rpoplpush('list5', 'list5')) # 33        print(client.lrange('list5', 0, -1)) # ['33', '5', '3', '4']        print(client.rpoplpush('notExist', 'list5')) # None        print(client.lrange('list5', 0, -1)) # ['33', '5', '3', '4']    except Exception as e:        print(e)    finally:        client.close()

brpop / blpop / brpoplpush 没在这里实现,详细可查看上篇文章(上面超链接)
