Flake8 for Python 3.x incompatible use of print operator

Runs hacking selecting only the error: H233 Python 3.x incompatible use of print operator

Fixing H233 issues

The 2to3 utility that ships with Python can automatically fix all print statements so that they are compatible with both Python 2 and Python 3.

At the root of your project, run 2to3 -f print . to see all the lines that need to be changed and then run 2to3 -f print -w . to actually write (-w) the changes into the files.
