As a simpler alternative, I suggest the launcher just gain a "--which" long option that displays the full path to the interpreter it found.

So: C:> py -2 --which C:\Python27\python.exe C:> py -3 --which C:\Python32\python.exe No significant complexity in the launcher, and if you want to add additional arguments like -m, -c, or -i you can do it by running '--which' and switching to invoking that interpreter directly. Perhaps even simpler would be for the -h option to print the interpreter paths which would be returned for -2 and -3, on separate lines, even without the --which, e.g. Currently configured: -2: c:\Python27\python.exe -3: c:\Python32\python.exe

--which is nice for people who can use Unix-style $() or Powershell & to directly execute the output as a command.

& (py -3 --which)
