Installation not compatiable with Python 2

[tsa87]

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

print is not a function in Python 2.x, causing a syntax error. Using from __future__ import print_function could make the code compatible with both versions.

Since the RDKit is also not compatible with Python 2 which itself has been deprecated for over a year, I expect this will be a futile exercise.
