Redis' Publish/Subscribe feature can be easily utilised with Python. Here is a simple example to guide you:

import redis

# Connect to Redis
r = redis.from_url(
  'rediss://default:<password>@<XXXXXX>.stackhero-network.com:<PORT_TLS>',
  health_check_interval=10,
  socket_connect_timeout=5,
  socket_keepalive=True,
  retry_on_timeout=True
)

# Create a PubSub instance
p = r.pubsub()

# Subscribe to the channel "test"
p.subscribe('test')

# Publish a message to the channel "test"
r.publish('test', 'This is a test message')

# Get the first available message from channel "test"
p.get_message()

# Unsubscribe from channel "test"
p.unsubscribe('test')
