<h2>Modules and the Python Standard Library</h2>

<p><strong>What is a module?</strong>  It's a Python program.  Many modules
have no main routine.  They are collections of related functions residing
in a file.  We have seen this with the <code>math</code>  module.</p>

<p><strong>Where can I see all of the Python modules?</strong>  They can be
found in the <a href="https://docs.python.org/3/py-modindex.html">Global 
Module Index</a> in the Python documentation.  These modules can do a
vast array of tasks for you.  You should look up the <code>math</code> module
and see its contents.</p>

<p><strong>Can I make my own module?</strong>  Yes.  We will see how to do 
this the smart way. </p>
