“Why is Python Installed on my Computer?” FAQ
*********************************************


What is Python?
===============

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 Lucasfilm Ltd.

Guide to Python.


Why is Python installed on my machine?
======================================

If you find Python installed on your system but don’t remember
installing it, there are several possible ways it could have gotten
there.

* 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.

* A third-party application installed on the machine might have been
  written in Python and included a Python installation.  There are
  many such applications, from GUI programs to network servers and
  administrative scripts.

* 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.

* Many Unix-compatible operating systems, such as Mac OS X and some
  Linux distributions, have Python installed by default; it’s included
  in the base installation.


Can I delete Python?
====================

That depends on where Python came from.

If someone installed it deliberately, you can remove it without
hurting anything.  On Windows, use the Add/Remove Programs icon in the
Control Panel.

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.

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.
