Redis - 错误:值不是有效的浮点数 [英] Redis - Error: value is not a valid float

问题描述

我在 Redis 中有一个排序集.我正在尝试通过在 Python 代码中使用 Zincrby 来更新特定元素的计数器值，例如:

I have a sorted set in Redis. I am trying to update the counter value of a specific element by using zincrby in Python code like:

conn.zincrby("usersSet", float(1), "user1")

但它显示的错误为:'错误:值不是有效的浮点数'

But it is showing an error as : 'Error: value is not a valid float'

我在 cli 上尝试了相同的命令:zincrby usersSet 1 users1它工作正常.Python代码中是否有其他方法可以增加排序集中特定键的计数器值.

I tried the same command on cli : zincrby usersSet 1 users1 And it is working correctly. Is there any other method in Python code to increase the counter value of the specific key in the sorted set.

推荐答案

redis-cli 和 python 连接器的参数顺序不同.你必须写 conn.zincrby("usersSet", "user1", 1)

Parameters order are differ between redis-cli and python connector. You have to write conn.zincrby("usersSet", "user1", 1)

python redis 库已更新以匹配 redis-cli 的顺序

The python redis library was updated to match redis-cli's order of arguments.

因此，conn.zincrby("usersSet", 1, "user1") 现在将是正确的用法.

Hence, conn.zincrby("usersSet", 1, "user1") will be the correct usage now.
