The most common use case for getting the current version of Redis using python is to ensure compatibility with the application code. Redis might introduce new features or deprecate old ones in different versions, so it's crucial to know the version currently running.
We can get the Redis server version by connecting to it and then using the INFO
command. Here's how you can do it using the redis-py
library:
import redis r = redis.Redis(host='localhost', port=6379, db=0) info = r.info() print('Redis Version: ', info['redis_version'])
In this example, we first establish a connection to the Redis server and then use the info()
function to fetch various information about the server as a dictionary. The current Redis version is stored under the redis_version
key in that dictionary.
Q: What other information can I get using the info()
function?
A: The info()
function returns a lot of useful information like uptime in seconds, connected clients, memory usage, etc.
