gevent with flask

1. Install Flask and gevent:

pip install Flask gevent

1. Import necessary modules in your Flask application:

from flask import Flask
from gevent.pywsgi import WSGIServer

1. Create a Flask application instance:

app = Flask(__name__)

1. Define a route and a simple handler function:

@app.route('/')
def hello():
    return 'Hello, World!'

1. Run the Flask application with the gevent WSGI server:

if __name__ == '__main__':
    http_server = WSGIServer(('', 5000), app)
    http_server.serve_forever()

1. Save the file and run your Flask application:

python your_app.py

Your Flask application will now be running using the gevent WSGI server on http://127.0.0.1:5000/.
