write me a python web simple one

Sure! Here is a simple example of a Python web application using the Flask framework:

from flask import Flask

app = Flask(__name__)

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

if __name__ == '__main__':
    app.run()

Save this code in a file named app.py. Then, you can run the web application by executing python app.py in your terminal. This will start a web server locally, and you can access the application by visiting http://127.0.0.1:5000/ in your web browser.

This example creates a basic Flask application with a single route that returns 'Hello, World!' when you visit the root URL. Feel free to expand on this example by adding more routes, templates, or functionality as needed.
