Bottle Web Framework

Bottle Logo

Bottle is a fast and simple WSGI-framework for the Python Programming Language. It offers request dispatching with url parameter support (routes), templates, key/value databases, a build-in HTTP server and adapters for many third party WSGI/HTTP-server and template engines - all in a single file and with no dependencies other than the Python Standard Library.

For news, bugs and documentation visit the bottle.py homepage.

Installation and Dependencies

You can install bottle with easy_install bottle or just download bottle.py and place it in your project directory. There are no (hard) dependencies other than the Python Standard Library.

Example

from bottle import route, run, request, response, send_file, abort, template

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

@route('/hello/:name')
def hello_name(name):
    return 'Hello %s!' % name

@route('/hello', method='POST')
def hello_post():
    name = request.POST['name']
    return 'Hello %s!' % name

@route('/static/:filename#.*#')
def static_file(filename):
    send_file(filename, root='/path/to/static/files/')

@route('/template/test')
def template_test():
    return template('template_name', title='Template Test', items=[1,2,3,'fly'])
    
run(host='localhost', port=8080)

Template example:

%message = 'Hello world!'
<html>
  <head>
    <title>{{title.title()}}</title>
  </head>
  <body>
    <h1>{{title.title()}}</h1>
    <p>{{message}}</p>
    <p>Items in list: {{len(items)}}</p>
    <ul>
    %for item in items:
      <li>
      %if isinstance(item, int):
        Zahl: {{item}}
      %else:
        %try:
          Other type: ({{type(item).__name__}}) {{repr(item)}}
        %except:
          Error: Item has no string representation.
        %end try-block (yes, you may add comments here)
      %end
      </li>
    %end
    </ul>
  </body>
</html>
