Bottle is a lightweight Python web micro-framework and template engine. It functions as a WSGI web framework that routes HTTP requests to Python functions to generate dynamic content.
The framework is distributed as a single Python file with no external dependencies. This minimalist distribution model allows for rapid application prototyping and the creation of web services with a small footprint.
The project provides capabilities for dynamic request routing, REST API development, and dynamic HTML rendering. It includes a built-in HTTP development server for web application hosting and a pluggable template system for injecting data into views.
