Redis in a Python App

Connect to Redis from Python with redis-py and use decode_responses to work with plain strings.

Install the client

redis-py is the standard, well-maintained client for Python.

pip install redis

Connect & use it

decode_responses=True returns plain Python strings instead of bytes — one less thing to convert.

import redis

r = redis.Redis(host="localhost", port=6379, decode_responses=True)
r.set("greeting", "hello", ex=60)
print(r.get("greeting"))   # hello
