How to append a slash with Bottle

append_slash.py

from bottle import hook, redirect, request

@hook('before_request')
def append_slash():
    if request.path.endswith('/'):
        pass
    else:
        redirect(request.path + '/')

# This function could also be written as...

    # @hook('before_request')
    # def append_slash():
    #     if not request.path.endswith('/'):
    #         redirect(request.path + '/')

# But I'm slightly annoyed by how "if not endswith" sounds.
# By the way, Guido, I think this example seemingly evinces that Python
# would benefit from accepting an "unless" keyword, as Perl and Ruby do.
