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 Lucasfilm Ltd.</p> <p>If you wish to learn more about Python, start with the <a class="reference external" href="http://wiki.python.org/moin/BeginnersGuide">Beginner’s Guide to Python</a>.</p> </div> <div class="section" id="why-is-python-installed-on-my-machine"> <h2>Why is Python installed on my machine?<a class="headerlink" href="#why-is-python-installed-on-my-machine" title="Permalink to this headline">¶</a></h2> <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://pysolfc.sourceforge.net/">PySol</a>, a solitaire game that includes over 1000 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"> <h2>Can I delete Python?<a class="headerlink" href="#can-i-delete-python" title="Permalink to this headline">¶</a></h2> <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 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> </div> </div> </div> </div> </div> <div class="sphinxsidebar"> <div class="sphinxsidebarwrapper"> <h3><a href="../contents.html">Table Of Contents</a></h3> <ul> <li><a class="reference internal" href="#">“Why is Python Installed on my Computer?” FAQ</a><ul> <li><a class="reference internal" href="#what-is-python">What is Python?</a></li> <li><a class="reference internal" href="#why-is-python-installed-on-my-machine">Why is Python installed on my machine?</a></li> <li><a class="reference internal" href="#can-i-delete-python">Can I delete Python?</a></li> </ul> </li> </ul> <h4>Previous topic</h4> <p class="topless"><a href="gui.html" title="previous chapter">Graphic User Interface FAQ</a></p> <h4>Next topic</h4> <p class="topless"><a href="../glossary.html" title="next chapter">Glossary</a></p> <h3>This Page</h3> <ul class="this-page-menu"> <li><a href="../bugs.html">Report a Bug</a></li> <li><a href="../_sources/faq/installed.txt" rel="nofollow">Show Source</a></li> </ul> <div id="searchbox" style="display: none"> <h3>Quick search</h3> <form class="search" action="../search.html" method="get"> <input type="text" name="q" /> <input type="submit" value="Go" /> <input type="hidden" name="check_keywords" value="yes" /> <input type="hidden" name="area" value="default" /> </form> <p class="searchtip" style="font-size: 90%"> Enter search terms or a module, class or function name. </p> </div> <script type="text/javascript">$('#searchbox').show(0);</script> </div> </div> <div class="clearer"></div> </div> <div class="related"> <h3>Navigation</h3> <ul> <li class="right" style="margin-right: 10px"> <a href="../genindex.html" title="General Index" >index</a></li> <li class="right" > <a href="../py-modindex.html" title="Python Module Index" >modules</a> |</li> <li class="right" > <a href="../glossary.html" title="Glossary" >next</a> |</li> <li class="right" > <a href="gui.html" title="Graphic User Interface FAQ" >previous</a> |</li> <li><img src="../_static/py.png" alt="" style="vertical-align: middle; margin-top: -1px"/></li> <li><a href="http://www.python.org/">Python</a> »</li> <li> <a href="../index.html">Python 2.7.5 documentation</a> » </li> <li><a href="index.html" >Python Frequently Asked Questions</a> »</li> </ul> </div> <div class="footer"> © <a href="../copyright.html">Copyright</a> 1990-2019, Python Software Foundation. <br /> The Python Software Foundation is a non-profit corporation. <a href="http://www.python.org/psf/donations/">Please donate.</a> <br /> Last updated on Jul 03, 2019. <a href="../bugs.html">Found a bug</a>? <br /> Created using <a href="http://sphinx.pocoo.org/">Sphinx</a> 1.1.3. </div> </body> </html>
