You can use the Flask-Caching extension along with Redis as a backend. First, install Flask-Caching and Redis.

What are the steps to install Flask-Caching and Redis?

You can install them using pip: pip install Flask-Caching redis. Then, configure your Flask app to use Redis.

How do I configure my Flask app to use Redis for caching?

In your Flask app, you can set it up like this:

from flask import Flask
from flask_caching import Cache

app = Flask(__name__)
app.config['CACHE_TYPE'] = 'redis'
app.config['CACHE_REDIS_URL'] = 'redis://localhost:6379/0'
cache = Cache(app)

Can you give me an example of caching a function result?

Sure! You can use the @cache.cached decorator:

@cache.cached(timeout=50)
def get_data():
    # Your data fetching logic here
    return data
