python hug api return custom http code

Found an example in their repo (https://github.com/berdario/hug/blob/5470661c6f171f1e9da609c3bf67ece21cf6d6eb/examples/return_400.py)

import hug
from falcon import HTTP_400

@hug.get()
def only_positive(positive: int, response):
    if positive < 0:
        response.status = HTTP_400

You can raise the falcon HTTPError, for example:

raise HTTPInternalServerError
