Using Redis with Python often involves performing operations like getting a string key. This is commonly used for retrieving specific data stored in a Redis database, such as user sessions, feature flags, or caching data.
import redis r = redis.Redis() r.set('mykey', 'myvalue') print(r.get('mykey')) # Output: b'myvalue'
This example shows how to set a value for a key (mykey
) and then retrieve this value using r.get('mykey')
.
import redis r = redis.Redis() print(r.get('non_existent_key')) # Output: None
In this example, we try to get a non-existent key from the Redis store. The get()
method returns None
when the key does not exist.
None
values.get()
on a key that holds non-string data types. Redis treats them differently and you might not get the result you expect.get()
returns None
, which can lead to TypeError in your application.What happens if the key does not exist? - If the key does not exist, Redis returns None
.
Can I use get()
with non-string data types? - While you can technically use it, the result might not be what you expect as Redis treats different data types differently.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
