Redis for Python - via Docker - No direct WSL

Pradeep Pep — Fri, 16 May 2025 15:19:42 +0000

Redis doesn’t officially support native Windows installations anymore. Instead of setting up WSL (Windows Subsystem for Linux), Docker is the easier and more modern way to run Redis on a Windows machine.

Installing Docker Desktop gives you a full environment where you can run Redis (and many other tools) without friction.

🔹 Step 1: Install Docker Desktop
Download and install Docker Desktop from:
https://www.docker.com/products/docker-desktop/

Once installed:
Make sure Docker is running (look for the whale icon in your system tray).
Enable WSL2 integration if prompted during installation.

🔹 Step 2: Pull and Run Redis
Open PowerShell or Command Prompt and run:

docker run --name my-redis -p 6379:6379 -d redis
docker ps

🔹 Step 3: Connect to Redis
docker exec -it my-redis redis-cli
set name "DockerRedis"
get name
ping

Install RedisInsight and connect to:
https://redis.io/insight/
Host: localhost
Port: 6379

To find out whether your Windows PC uses an ARM64 or AMD64 (also called x64) architecture, follow these
from Command Prompt you can run:

C:\Users\pepsara>echo %PROCESSOR_ARCHITECTURE%

AMD64

✅ Step-by-Step: Use Redis with Python in VS Code
🔧 1. Install Redis client for Python
In your terminal (inside VS Code), run:
pip install redis

🧪 2. Test Redis Connection in Python
Create a new Python file, e.g., redis_test.py, and add the following code:
import redis

Connect to Redis

r = redis.Redis(host='localhost', port=6379, db=0)

Set a key

r.set('mykey', 'Hello Redis!')

Get the key

value = r.get('mykey')
print(value.decode('utf-8')) # Output: Hello Redis!

Then run it: python redis_test.py
You should see: Hello Redis!

4.Swap the values of two variables x and y without using a third variable. Print their values before and after swapping.

5.Define constants PI with appropriate values and print them.
Ans: constants are typically written in all uppercase letters with underscores separating words. However, Python does not enforce this, so constants are not truly immutable. You can still override.

Ans: ** is Squared

7.Define constants for the length and width of a rectangle. Calculate and print the area.
