Flask Documentation

Welcome to the Flask documentation page! Flask is a micro web framework for Python based on Werkzeug and Jinja 2. It's a very simple and easy-to-use framework that is perfect for small to medium-sized web applications.

Features

Micro Framework: Flask is a micro framework, which means it doesn't include tools for database interaction, form validation, or anything else. This allows you to choose the tools you need for your project.
Flexible: Flask is highly flexible and can be extended with various extensions.
Fast: Flask is known for its speed and efficiency.

Quick Start

Here's a simple 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 with Python. You should see a message saying "Hello, World!".
