I suppose we tell all our windows users (which I'm not) to be sure to have python in their PATH. So they should have used the installer facility for that. > Are you familar with the py.exe Windows launcher?

One of our constraint is that we use Cygwin's bash and now, every user relies on the shebang. The problem reduce to this. Assuming you are in a bash window (whether on cygwin or ubuntu 18, or mac os) and you do this: > ./myScript.py How do you write the shebang so it runs reliably python3 with the minimal amount of energy spent configuring the system.

All our scripts would work out of the box, given our workflow. From that doc: https://docs.python.org/3/using/windows.html#the-microsoft-store-package It seems `python3.exe` is available when we installed python from the windows store. So maybe a solution is that we tell our employees to install that version instead. That is just a bit odd the _traditional installer_ does not do the same thing. _______________________________________________ Python-ideas mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/5V4AJGK3HFKM7XGCLZUA75K2OTAJN5QO/ Code of Conduct: http://python.org/psf/codeofconduct/
