Bottle: Python Web Framework¶
Bottle is a fast, simple and lightweight WSGI micro web-framework for Python. It is distributed as a single file module and has no dependencies other than the Python Standard Library.
Routing: Requests to function-call mapping with support for clean and dynamic URLs.
Templates: Fast and pythonic built-in template engine and support for mako, jinja2 and cheetah templates.
Utilities: Convenient access to form data, file uploads, cookies, headers and other HTTP features.
Server: Built-in HTTP development server and support for a wide range of WSGI capable HTTP server (e.g. gunicorn, paste or cheroot).
Example: “Hello World” in a bottle
from bottle import route, run, template
@route('/hello/<name>')
def index(name):
return template('<b>Hello {{name}}</b>!', name=name)
run(host='localhost', port=8080)
Run this script or paste it into a Python console, then point your browser to http://localhost:8080/hello/world. That’s it.
Download and Install¶
Install the latest stable release with pip install bottle or download bottle.py (unstable) into your project directory. There are no hard [1] dependencies other than the Python standard library.
Dead Snakes¶
Bottle up to version 0.12 supported an absurd range of Python versions, some of which reached their end-of-life well over a decade ago. Starting with Bottle 0.13 we ensure backwards compatibility with maintained versions of Python only. Outdated Python versions may still work, but are no longer tested for compatibility.
If you are in the unfortunate position to have to rely on “dead snakes” for production, just stick with Bottle 0.12 (LTS) or whichever release of Bottle still supports it. Everyone else should upgrade regularly to benefit from new features and improvements.
