I wonder if it will make the life easier if Python was installed with .py association to "%PYTHON_HOME%\python.exe" "%1" %* It will remove the need to run .py scripts in virtualenv with explicit 'python' prefix.
In Python 3.3 and later, the "py.exe" launcher is installed, and this is the association for ".py" files by default. It looks at the #! line of .py files, so you can run a specific Python interpreter by giving its full path. You can also specify (for example) "python3" or "python3.2" to run a specific Python version.
Yes, I've noticed that this nasty launcher gets in the way. So, do you propose to edit source files every time I need to test them with a new version of Python? My original user story:
I want to execute scripts in virtual environment (i.e. with Python installed for this virtual environment) without 'python' prefix.
Here is another one. Currently Sphinx doesn't install with Python 3.2 and with Python 3.3 . Normally I'd create 3 environments to troubleshoot it and I can not modify all Sphinx files to point to the correct interpreter to just execute 'setup.py install'.
A solution would be to teach launcher to honor PYTHON_PATH variable if it is set (please don't confuse it with PYTHONPATH which purpose is still unclear on Windows).
