Connect with Python

This example connects to Redis service from Python, making use of the redis-py library.

Variables

These are the placeholders you will need to replace in the code sample:

Variable

Description

REDIS_URI

URL for the Redis connection, from the service overview page

Pre-requisites

Install the redis-py library:

pip install redis

Code

Create a new file named main.py, add the following content and replace the placeholder with the Redis URI:

import redis


def main():
    redis_uri = 'REDIS_URI'
    redis_client = redis.from_url(redis_uri)

    redis_client.set('key', 'hello world')
    key = redis_client.get('key').decode('utf-8')

    print('The value of key is:', key)


if __name__ == '__main__':
    main()

This code creates a key named key with the value hello world and no expiration time. Then, it gets the key back from Redis and prints its value.

Run the code:

python main.py

Note

Note that on some systems you will need to use python3 to get Python3 rather than the previous Python2

If the script runs successfully, the outputs should be:

The value of key is: hello world
