Translating a skill is pretty easy. It works the same way as training data. You’ll just have to use the decorator on a method which returns a dictionary representing keys and associated translations.

from pytlas import translations, intent

def my_translations(): return {
  'Turning lights on in %s': "J'allume les lumières dans %s",

# Training data are not shown here

def my_handler(request):
  room = request.intent.slot('room').first().value

  # Do something

  # Here, just use the `request._` to translate the string
  # If you wish to localize a date, we got you covered with the `request._d`

  request.agent.answer(request._('Turning lights on in %s') % room)

  return request.agent.done()
