<h2>The new <code>match</code> Boss Statement</h2> <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>
