Find tutorials, examples and technical articles that will help you to develop with Redis and Python.

Getting Started​

The Python community has built many client libraries that you can find here . For your first steps with Python and Redis, this article will show how to use the recommended library: redis-py

Step 1. Run a Redis server​

Redis is an open source, in-memory, key-value data store most commonly used as a primary database, cache, message broker, and queue. Unlike relational databases, Redis database delivers sub-millisecond response times, enabling fast and powerful real-time applications in industries such as gaming, fintech, ad-tech, social media, healthcare, and IoT.

Redis (also called remote dictionary server) is a multi-model database, and provides several built-in data structures/data type such as Lists, Hashes, Geospatial indexes, Strings, Sets etc. You can either run Redis server in a Docker container or directly on your machine. Follow the below command line to setup a Redis server on Mac OS:

 brew tap redis-stack/redis-stack
 brew install --cask redis-stack
INFO

Redis Stack unifies and simplifies the developer experience of the leading Redis modules and the capabilities they provide. Redis Stack bundles five Redis modules: RedisJSON, RedisSearch, RedisGraph, RedisTimeSeries, and RedisBloom Learn more

Ensure that you are able to use the following Redis command to connect to the Redis instance.

 redis-cli
 127.0.0.1:6379>

Now, you should be able to get Redis data by using Redis commands.

Step 2. Install the Redis client library using pip​

The following Python code allows you to connect to the default Redis server instance .

 pip3 install redis

Step 2. Write your application code​

 import redis

 pool = redis.ConnectionPool(host='localhost', port=6379, db=0)
 redis = redis.Redis(connection_pool=pool)

 redis.set('mykey', 'Hello from Python!')
 value = redis.get('mykey')
 print(value)

 redis.zadd('vehicles', {'car' : 0})
 redis.zadd('vehicles', {'bike' : 0})
 vehicles = redis.zrange('vehicles', 0, -1)
 print(vehicles)
