[Tutor] Side effect and return value

[Albert-Jan Roskam]

   Hi,
   I've just read "Code that fits into your Brain".
   The author says a function with a side effect should not have a return
   value. But how would one write this function in order to do that? This
   looks totally fine to me:
   from uuid import UUID
   from requests import post
   def create_user(info: dict) -> UUID:
       resp = post("https://some-thing/user", json=info)
       resp.raise_for_status()
       return UUID(resp.json()["id"])
   Thanks!
   AJ
