We will start our intro to redis via using docker compose. Create a docker-compose.yml file and add the following.

version: "3.8"
services:
  redis:
    image: "redis:alpine"
    command: redis-server
    ports:
      - "6379:6379"
    volumes:
      - $PWD/redis-data:/var/lib/redis
      - $PWD/redis.conf:/usr/local/etc/redis/redis.conf
    environment:
      - REDIS_REPLICATION_MODE=master
Ensure you have docker installed and run

docker-compose up
Installing Redis Modules
In python, the main used redis module is called redis-py and can be installed using the follows.

pip install redis
Writing the Code
Let's open up a new file, index.py and go through many of the common commands you will used with lists in redis.

pipeline = r.pipeline()
Next, we can append our commands to this pipeline. For example, here are a series of counter operations. Each of these commands will be appeneded to our pipeline and not sent.

pipeline.set("count-user1", 1)
pipeline.del("count-user1-old-day")
pipeline.get("count-user1")
pipeline.incr("count-user1")
pipeline.get("count-user1")
Finally, to send all commands, we can use the exec function on the pipeline. Redis will execute all the commands and returns the results in an array.

pipeline.execute()
print(results)

// [
//   [ null, 'OK' ],
//   [ null, 0 ],
//   [ null, '1' ],
//   [ null, 2 ],
//   [ null, '2' ]
// ]
Below is the full code for context.

import redis

r = redis.Redis(host='localhost', port=6379, db=0)

pipeline = r.pipeline()

pipeline.set("count-user1", 1)
pipeline.del("count-user1-old-day")
pipeline.get("count-user1")
pipeline.incr("count-user1")
pipeline.get("count-user1")

results = pipeline.execute()
print(results)
