Bottle.py error routing

Question

Bottle.py ships with an import to handle throwing HTTPErrors and route to a function.

Firstly, the documentation claims I can (and so do several examples):

In some cases I find it's better to subclass Bottle. Here's an example of doing that and adding a custom error handler.

#!/usr/bin/env python3
from bottle import Bottle, response, Route

class MyBottle(Bottle):
    def __init__(self, *args, **kwargs):
        Bottle.__init__(self, *args, **kwargs)
        self.error_handler[404] = self.four04
        self.add_route(Route(self, "/helloworld", "GET", self.helloworld))
    def helloworld(self):
        response.content_type = "text/plain"
        yield "Hello, world."
    def four04(self, httperror):
        response.content_type = "text/plain"
        yield "You're 404."

if __name__ == '__main__':
    mybottle = MyBottle()
    mybottle.run(host='localhost', port=8080, quiet=True, debug=True)
