def autodelegate(prefix=''):
assistant
#Here is the Python program you requested.

    """Returns a method that takes one argument and calls the method named prefix+arg,
    calling `notfound()` if there isn\t one. Example:
    urls = (\/prefs/(.*)\, \prefs\)
    class prefs:
    GET = autodelegate(\GET_\)
    def GET_password(self): pass
    def GET_privacy(self): pass
    `GET_password` would get called for `/prefs/password` while `GET_privacy` for
    `GET_privacy` gets called for `/prefs/privacy`.
    If a user visits `/prefs/password/change` then `GET_password(self, \/change\)`
    is called.
