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()
