Now let's try working with Redis from Python. First, make sure to install the redis-py driver:
pip install redis
It is also recommended to install Hiredis along with redis-py. Hiredis is a parsing class written by the core Redis team, and redis-py will use Hiredis if it is present. Its use can provide a significant performance gain over the default PythonParser. The hiredis parser can be installed similarly via pip:
pip install hiredis
Let's write a simple script to set, get, and output a simple welcome message. Create a new Python script and call it redisHelloWorld.py.
First, we will add our imports. We will need StrictRedis, as well as the sys module to pull in command-line arguments:
from redis import StrictRedis import sys
