 You can find these packages by googling for with the term "<subject> python library".  For example "spell check python library".  This turns up [https://pythonhosted.org/pyenchant/ | PyEnchant] which describes how to use and access the library.  There are probably others.  You can also go to the [[https://pypi.python.org/pypi|Python Package Index]].  What ever you do, make sure you use the correct version of the library for the version of Python you're using (in our case, Python 3)
 To use this external package in code, you use the !`import` keyword in Python like so:
+To use the pyenchant external package in your program, you use the !`import` keyword in Python at the beginning of your program like so:
 {{{
 …
 good=d.check("Hello")  # Correctly spelled word returns True
 }}}
+This makes the library known to your code once its installed.
 It would be a enormous effort to create your own spell check library, so reusing one saves a lot of time.   We'll be using this when we program robots because a lot of the work we need to do to communicate with the parts of a robot has already been done.  And we want to spend time making robots do things, not figuring out how to communicate with then.
