selenium 'NoSuchElementException'

http://stackoverflow.com/questions/19200497/python-selenium-webscraping-nosuchelementexception-not-recognized

Error here:

NameError: name 'NoSuchElementException' is not defined

Googling/documentation came up with nothing...and it strikes me as strange that selenium is fine throwing an exception but can't catch it.

from selenium.common.exceptions import NoSuchElementException
