Hello Paul,
I modified the SDK Python wrapper to work with Python 2 and 3.
A decorator is used to have clean code and to handle functions with arbitrary parameters (instead of adding .decode() and .encode() everywhere).
You can find it here:

I saw that the two functions mentioned above
ssc.data_set_matrix_from_csv()
ssc.build_info()
area available in the file PySSC.py created by the code generator,
but not in sscapi.py that comes with sam-sdk-2016-3-14-r3.
