[AWQ]Hidden good Python books

  In this AWQ ("answers without questions") I will write about
  "hidden good Python books" - Good books about Python subjects
  which are hidden from our view.

  Where would you hide a book? In another book!

  So, the best book about tkinter for beginners is hidden in
  "Programming Python" (2010 or maybe later) by Mark Lutz as
  "Part III: GUI Programming". So don't go looking for a book
  "tkinter for Beginners", get "Programming Python" instead!

  And the best book about asyncio can be found in "Fluent Python"
  (2014 or 2015 or maybe later) by Luciano Ramalho, hiding
  in "Part V: Control flow".

  Summarizing, I can say: Today we learned about two outstanding
  Python books, one about tkinter and one about asyncio, hidden
  in books with titles that do not give this away.
