Getting ready

First we need to install Selenium.  We do this with our trusty pip:

~ $ pip install selenium
Collecting selenium
 Downloading selenium-3.8.1-py2.py3-none-any.whl (942kB)
 100% |████████████████████████████████| 952kB 236kB/s
Installing collected packages: selenium
Successfully installed selenium-3.8.1

This installs the Selenium Client Driver for Python (the language bindings). You can find more information on it at https://github.com/SeleniumHQ/selenium/blob/master/py/docs/source/index.rst if you want to in the future.

For this recipe we also need to have the driver for Firefox in the directory (it's named geckodriver).  This file is operating system specific.  I've included the file for Mac in the folder. To get other versions, visit https://github.com/mozilla/geckodriver/releases.

Still, when running this sample you may get the following error:

FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver'

If you do, put the geckodriver file somewhere on your systems PATH, or add the 01 folder to your path. Oh, and you will need to have Firefox installed.

Finally, it is required to have PhantomJS installed.  You can download and find installation instructions at: http://phantomjs.org/
