Description
Trying to test a python problem in QGIS3 via python on cli in osgeo4w64 (installed via osgeo4w installer in c:\\osgeo4w64), I open a commandbox by running the bat file:
c:\\osgeo4w64\\OSGeo4W.bat
Then trying to start python3, I get the following (see also screendump)
(This is on WindowsServer2008 machine.)
GDAL 2.1.3, released 2017/20/01
C:\\osgeo4w64>python3

Some googling:
apperently it is mixing python2 and python3 stuff, because python2 is in path?
Indeed when I type:
C:\\osgeo4w64>path
PATH=C:\\OSGEO4~1\\apps\\Python27\\Scripts;C:\\OSGEO4~1\\bin;C:\\Windows\\system32;C:\\Windows;C:\\Windows\\WBem;C:\\OSGEO4~1\\apps\\msys\\bin
it is pointing to the Python27 dir?
maybe a more thorough cleanup of PATH (only for python3.bat/bin?)

1. Not a QGIS issue.
2. run call py3_env.bat first (also call qt5_env.bat if you want to use PyQt5)
3. use python-qgis.bat (that runs both and provides the environment to import qgis)
