<h1 class="title">"Why is Python Installed on my Computer?" FAQ</h1>
<div class="section" id="what-is-python">
<h1>What is Python?</h1>
<p>Python is a programming language. It's used for many different
applications. It's used in some high schools and colleges as an
introductory programming language because Python is easy to learn, but
it's also used by professional software developers at places such as Google,
NASA, and Industrial Light & Magic.</p>
<p>If you're curious about finding out more about Python, start with the
<a class="reference external" href="http://www.python.org/moin/BeginnersGuide">Beginner's Guide to Python</a>.</p>
</div>
<div class="section" id="why-is-python-installed-on-my-machine">
<h1>Why is Python installed on my machine?</h1>
<p>If you find Python installed on your system but don't remember
installing it, there are several possible ways it could have gotten
there.</p>
<ul class="simple">
<li>Perhaps another user on the computer wanted to learn programming
and installed it; you'll have to figure out who's been using the machine
and might have installed it.</li>
<li>A third-party application installed on the machine might have been written
in Python and included a Python installation. For a home computer,
the most common such application is
<a class="reference external" href="http://www.oberhumer.com/opensource/pysol/">PySol</a>,
a solitaire game that includes over 200 different games and variations.</li>
<li>Some Windows machines also have Python installed. At this writing we're
aware of computers from Hewlett-Packard and Compaq that include Python.
Apparently some of HP/Compaq's administrative tools are written in Python.</li>
<li>All Apple computers running Mac OS X have Python installed; it's included
in the base installation.</li>
</ul>
</div>
<div class="section" id="can-i-delete-python">
<h1>Can I delete Python?</h1>
<p>That depends on where Python came from.</p>
<p>If someone installed it deliberately, you can remove it without
hurting anything. On Windows, use the Add/Remove Programs icon in the
Control Panel.</p>
<p>If Python was installed by a third-party application, you can also
remove it, but that application will no longer work. You should probably
use that application's uninstaller rather than removing Python directly.</p>
<p>If Python came with your operating system, removing it is not
recommended. If you remove it, whatever tools were written in Python
will no longer run, and some of them might be important to you.
Reinstalling the whole system would then be required to fix things
again.</p>
