Python is a general-purpose, high-level programming language. It is also a type of snake, but one is arguably more suitable for behavioral research than the other.

Installation

Windows (32 bit)

Download the Win32 installer
Double-click on the executable and follow the steps on your screen.

Configuration

Windows Environment Variables

Computer --> Properties --> Advanced settings --> Environment Variables.

Add the following Path:

C:\Python27;C:\Python27\Lib\site-packages\;C:\Python27\Scripts\;

Package Management

After Python is installed, you can use 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 get-pip.py
Execute get-pip by entering the following command: python get-pip.py

To install a package, simply execute the following command: c:\pip install PACKAGE_NAME
Replace PACKAGE_NAME with the name of the package of choice.

Note: By default, packages are installed in the following folder (Windows):

C:\Python27\Lib\site-packages

This location may differ if you have installed Python somewhere else.
