Redis-py

Redis-py is The Python interface to the Redis key-value store.

The library encapsulates an actual TCP connection to a Redis server and sends raw commands, as bytes serialized using the REdis Serialization Protocol (RESP), to the server. It then takes the raw reply and parses it back into a Python object such as bytes, int, or even datetime.datetime.

Installation⚑

pip install redis

Usage⚑

import redis
r = redis.Redis(
    host='localhost',
    port=6379,
    db=0,
    password=None,
    socket_timeout=None,
)

The arguments specified above are the default ones, so it's the same as calling r = redis.Redis().

The db parameter is the database number. You can manage multiple databases in Redis at once, and each is identified by an integer. The max number of databases is 16 by default.

Common pitfalls⚑

  • Redis returned objects are bytes type, so you may need to convert it to string with r.get("Bahamas").decode("utf-8").
