Python fixes

[d3x0r]

Why hasn't this been updated to python3? Why can I never get this to build without these changes? Updates to Python3 syntax for exceptions and execfile -> exec( open( file ).read() ) (and then subsequent changes between binary buffers and strings with .encode/.decode('utf-8')

I think because the buildbot uses Python 2.7

@GnorTech Please advise

@d3x0r What Python version are you using? The build environment uses v3.11.2 (http://buildbot.nwjs.io:8010/#/about)

well ya know - part of the problem is sample docs actually refer to nw17 which is absolutely ancient. Later my issue was the tags/branches were missing in the repository for the last versions so the pull script couldn't get the synced versions.

Edit : I can't be positive what the state of the version I was trying to build was... I was trying to use python 3; but the script was written for 2; hence the complaint 'why is there still 2.7 python scripts that need updates'
