Flask is a micro web framework for Python based on Werkzeug and Jinja 2. It's a very popular choice for building web applications due to its simplicity and flexibility.

Features

  • Routing: Flask provides a simple way to define routes and associate them with functions.
  • Templates: Jinja 2 is used for templating, allowing you to create dynamic web pages.
  • Extensions: Flask has a rich ecosystem of extensions that provide additional functionality.

Quick Start

Here's a basic example of a Flask application:

from flask import Flask

app = Flask(__name__)

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

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

To run this application, save the code to a file named app.py and execute it. The application will start on http://127.0.0.1:5000/.
