Python is a widely used general-purpose, high-level programming language.

== Getting Started ==
=== Python Versions ===
Most modern *NIX systems ship with a default version of Python. If the default version is not sufficient, there are multiple version of Python are available via [[Modules | GNU Modules]]. If you find that you need a version of Python that is not currently available through GNU Modules, you can always build it from [https://www.python.org/downloads/ source].

=== Python Environment ===
Information about PYTHONPATH

=== Installing Modules ===
While some of the Versions of Python available in GNU modules provide a default set of modules pre-installed, you may wish to install your own. Typically you will not have access to the global Python install location, so you will have to install modules using an alternative method.
==== Unix/Linux Alternate Module Installation====
===== 'User' scheme=====
The user scheme will install the module into the site userbase (<code>python -c 'import site; print site.USER_BASE'</code>). This file location is included in the PYTHONPATH by default.
<pre>bash:~$ python setup.py install --user</pre>
====='Prefix' scheme=====
The prefix scheme will install the module into a location specified by the user. This location will need to be added to the PYTHONPATH in order for the module to be found by python.
<pre>bash:~$ python setup.py install --prefix="/path/to/location"</pre>
=====[[PythonVirtualEnv | Python Virtual Environment]]=====
Virtual environments are cool, use them.
