Here's what it looks like:

::

  import dramatiq
  import requests


  @dramatiq.actor
  def count_words(url):
       response = requests.get(url)
       count = len(response.text.split(" "))
       print(f"There are {count} words at {url!r}.")


  # Synchronously count the words on example.com in the current process
  count_words("http://example.com")

  # or send the actor a message so that it may perform the count
  # later, in a separate process.
  count_words.send("http://example.com")

**Dramatiq** is :doc:`licensed<license>` under the LGPL and it
officially supports Python 3.7 and later.
