From a Python venv, find installation from which the venv command was run

Question

Given a Python virtual environment created with pythonXY_EXE -m venv venv , how do I find the python executable PythonYX_EXE used to create the virtual environment?

Solutions for both MS-Windows and Linux are sought.

For Linux, I can come up with a solution by resolving the symlink with readlink -f venv/bin/python . But for MS Windows?

A non-answer is the official Creation of virtual environments :

... pyvenv.cfg file in it with a home key pointing to the Python installation from which the command was run

My goal: Running python without copy/symlink, as those may fork multiple processes.

Answer 1

On MS Windows, by inspecting the source code of the venv library , the executable is located at (if symlinks are not enabled or failed)

<home-key-of-pyvenv.cfg-file>/python.exe.
