Well, changes to the launcher will not typically break any existing code, but constant changes in behaviour may still be a cause of confusion and be hard to explain, à la: "since Python 3.5 the launcher supports virtual environments, but the details of this support differ between 3.5 and 3.6, e.g. in 3.5, scripts with a python3 shebang line will be executed by the system python3 independent of the virtual environment, but in 3.6 a virtual environment python3 interpreter will be used." IMO it would be preferable to have all virtualenv related changes happening with one release. > As a start, maybe the > Python Windows installer should be writing a "python3.exe" as well as > "python.exe" and venv should put that in the virtualenv.

Seems pretty simple and unproblematic to me and it might actually be useful to know the interpreter version without running it in other places besides the launcher. What do the pypa devs think about this? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23465> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
