To connect to a Redis database in Python, you can use the redis library. Here's a step-by-step guide on how to connect to a Redis database in Python:

1. Install the redis library by running the following command:

1

pip install redis

1. Import the redis library in your Python script:

1

import redis

1. Create a Redis connection by specifying the host, port, and database number:

1
2
3
4
5

redis_host = 'localhost'
redis_port = 6379
redis_db = 0

r = redis.Redis(host=redis_host, port=redis_port, db=redis_db)

1. You can perform various operations on the Redis database using the r object. Here are some examples:

1
2
3
4
5
6
7
8
9

# Set a key-value pair in the database
r.set('key', 'value')

# Get the value of a key
value = r.get('key')
print(value)

# Delete a key
r.delete('key')

1. You can also use Redis commands directly using the r object. For example:

1
2
3
4

# Add an item to a list
r.rpush('mylist', 'item1')

# Get all items from a list
items = r.lrange('mylist', 0, -1)
print(items)

That's it! You have successfully connected to a Redis database in Python and can start interacting with it using the redis library.
