    It's a difference between Python 2 and Python 3.

    Normally a lot of care is taken to maintain backwards compatibility,
    but it was decided that the language needed to be tidied up and certain
    misfeatures removed.

    Python 2 has stopped at version 2.7. Python 3 is currently at version
    3.3.
