Summary ======= It is now time to review what we have learned since the last Summary. We have seen our first Python keywords, ``def``, ``from``, ``import``, and how to save functions in a library to be used later. We have seen the concept of looping, and a keyword unique to Reeborg's World: ``repeat``. We have seen five functions specific to Reeborg's World: - ``move()`` - ``turn_left()`` - ``take()`` - ``put()`` - ``pause()`` We are now ready to learn about some very important programming concepts dealing with deciding automatically between different possibilities.
