flask

Flask is a lightweight WSGI web application framework for Python. It aims to make getting started quick and easy while still supporting growth into complex applications. Flask began as a simple wrapper around the Werkzeug WSGI toolkit and the Jinja templating engine, and has since become one of the most widely used Python web frameworks. The framework is intentionally unopinionated: it offers suggestions but does not enforce dependencies or a particular project layout. Developers are free to select the libraries and tools that fit their needs. A large ecosystem of community-provided extensions makes it simple to add functionality such as database integrations, authentication, and APIs. A minimal Flask application can be written in a few lines: ```python from flask import Flask app = Flask(__name__) @app.route("/") def hello(): return "Hello, World!" ``` Running the built-in development server is done with `flask run`, which serves the app locally by default. The project is developed and supported by the Pallets organization, and the README includes sections on donating and contributing. Contribution guidelines cover reporting issues, requesting features, asking or answering questions, and submitting pull requests.
