Python Redis
Python Redis:
Python provides a library called “redis-py” that allows you to interact with Redis, an open-source in-memory data structure store. Redis is often used as a caching layer or as a message broker in various applications.
To use Redis in Python, you need to install the redis package.
You can do this by running the following command:
pip install redis
Once you have installed the package, you can start using Redis in your Python code.
Here’s a basic example that demonstrates how to connect to Redis, set a value, and retrieve it:
import redis
# Connect to Redis
r = redis.Redis(host='localhost', port=6379, db=0)
# Set a key-value pair
r.set('mykey', 'Hello Redis!')
# Retrieve the value
value = r.get('mykey')
print(value.decode()) # Output: Hello Redis!
In this example, we create a Redis object and connect to a Redis server running on the localhost with the default port (6379). We then use the set method to store a key-value pair, and the get method to retrieve the value. The value returned by Redis is a bytes object, so we use the decode() method to convert it to a string.
This is just a basic example, and Redis offers a wide range of data structures and operations you can use. The redis-py library provides methods for working with strings, lists, sets, sorted sets, hashes, and more.
You can refer to the official documentation of redis-py for more information on how to use Redis in Python: https://redis-py.readthedocs.io/
