Package Management

After Python is installed, you can use pip to install your required packages. pip is included with Python 2.7.9 or newer. For older versions, use the following steps to install:

  1. Download get-pip.py
  2. 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.
