Ray: I think this proposal is good to recommend Python3 as the default interpreter. I summary the updated proposal.
1. PYTHON3_ENABLE env is not set. edksetup.bat/edksetup.sh will find higher version python installed in OS. If Python3 is found, Python3 will be used. Then, if python2 is found, and python2 is used. If not found, report error and stop build. This will change the default python interpreter from Python2 to Python3 when they both are installed. 2. PYTHON3_EANBLE env is set to TRUE. edksetup.bat/edksetup.sh will find Python3. If Python3 is found, Python3 will be used. If not found, report error and stop build. 3. PYTHON3_ENABLE env is set to not TRUE. edksetup.bat/edksetup.sh will find Python2. If Python2 is found, Python2 will be used. If not found, report error and stop build. Once Python is found, edksetup.bat/edksetup.sh and build tool will both print message to let user aware which version python tool is used in this build.
