Tutoring Schedule for Fall 2016. The recommended tutors for this calss are Matt Gavin and Kendra Campbell McCalla.
Please note that the version of Python that we are using for this class is Python 2 (2.7 to be exact), and NOT Python 3. Python 2 is still standard on Linux, Macs and is used by most applications programmers. Program examples will not work with Python 3 without adjustments. Make sure you install and use Python 2 (default on Macs and Linux, use above links for Windows).
