===Package Management===

==== pip ====
After Python is installed, you can use [[wikipedia:Pip_(package_manager)|pip]] to install your required packages. '''pip is included with Python 2.7.9 or greater'''. For older versions, use the following steps to install:

# Download [https://raw.github.com/pypa/pip/master/contrib/get-pip.py get-pip.py]
# Execute get-pip by entering the following command: <code style="background-color:#000; color:#fff; padding:1px 3px;">python get-pip.py</code>

To install a package, simply execute the following command: <code style="background-color:#000; color:#fff; padding:1px 3px;">c:\pip install PACKAGE_NAME</code><br/>
Replace PACKAGE_NAME with the name of the package of choice.

'''Note:''' By default, packages are installed in the following folder (Windows):
<pre>C:\Python27\Lib\site-packages</pre>
This location may differ if you have installed Python somewhere else.

==== Setuptools ====
For package management with setuptools, install setuptools using the following command: <code style="background-color:#000; color:#fff; padding:1px 3px;">pip install -U setuptools</code>

To install a package, simply execute the following command: <code style="background-color:#000; color:#fff; padding:1px 3px;">c:\easy_install PACKAGE_NAME</code><br/>
Replace PACKAGE_NAME with the name of the package of choice.
