Of course if, rather than creating symlinks, you create a batch file called
python3.bat and containing the line:
@py -3 %*
Then save it to somewhere on your path, e.g. the python scripts directory, then
issuing, from the command line or another batch file the command python3 should
just work (as long as the chosen location is earlier in the path than
%appdata%\..\Local\Microsoft\WindowsApps\ which is where the python3.exe app
store launcher lives).
As the py launcher works just find in MinGW you can either do the same with a
bash script or an alias and the Windows System For Linux allows you to install
python3 as well as python (on my system the latest versions are 3.5.1-3 &
2.7.12-1).
It is also worth mentioning that python (and the py launcher) both accept
windows paths (\ separated) and *nix paths (/ separated) from the command line
and that from within scripts the *nix path separator is to be preferred as it
will not require either being in a r-string or escaped i.e. you can use
glob.glob(r"C:\Users\Gadget\*.docx") or
glob.glob("C:\\Users\\Gadget\\Documents\\*.docx") but are better off using
glob.glob("C:/Users/Gadget/Documents/*.docx") - the only real issue to avoid is
the fact that Windows paths are case insensitive so names that differ only in
case changes can & will collide.

Thanks. Sure, there are many ways to fix this manually, or work around it.
Would be great if it was consolidated, with one command "to rule them all."
