Getting a "raise WebDriverException" running Selenium Python for Firefox on Windows 7

I keep getting Python errors trying to execute the following simple Selenium Python code for Firefox on a Windows 7 system.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.python.org")

I could not find any previous questions related to Windows, and so I am trying to find out if anyone can help me solve this problem.

I uninstalled Python 3.4 and installed the latest Python 3.5 to no avail.

Here's the complete error message:
