Hola,
Great courses. I figure it might be worth noting, somewhere perhaps in the course, that with python 3 the autos.py will break on line 150.

In the code & Python 2:
for field, val in row.iteritems():
for Python 3, as I'm sure you're aware, it is now:
for field, val in row.items():
I didn't know if there was a better place to put this. Cheers.
