Using Python launcher for Windows to select a binary in the Scripts directory

Question

Python launcher for Windows can find Python installations and select a particular version of the interpreter to run:

c:/>py -3.4

Is it possible to select some other binary from the installation?

For example nose, behave, nuitka, and many others install a script or binary which can be run directly, if the Script directory in on the path. e.g:

c:/behave

Can py be used to select which behave to call?

I know I can instead select a whole virtualenv, but I was wondering whether py has more uses than selecting the interpreter binary.

I've wondered this too, but PEP 397 says that it's for choosing the right python executable, and doesn't mention anything about any binaries that may be included with installed packages in the python path.

https://www.python.org/dev/peps/pep-0397/

The only way I've solved this is through virtual environments, like you mentioned.
