In Windows the provided methods for running complex command lines are either a batch file or a shortcut.Someone very kindly pointed out to me in this thread that there is a PEP for py.exe. I don't use py.exe originally because I didn't trust it believing it was a new-fangled Microsoft trick. I did read that PEP but it has no relevance for my mixed Windows/Linux environments. On reflection I now believe I won't use py.exe because it introduces an unnecessary layer of indirection.The bottom line is that you still need to know which Python a particular set of circumstances demands and if you use py.exe you then need to also understand how it chooses and how it interprets shebang lines written for your Linux environment. And if that isn't your situation I have jumped to the wrong conclusion.I have found no problem in Windows when I use shebang lines in scripts intended for execution in both Linux and Windows. They are ignored unless you use py.exe.My advice is to give up py.exe unless your use case mandates shebang lines in Windows.M--(Unsigned mail from my phone)

Only thing I can think of - and I don't really believe in that idea: as far as I know in Windows 11 the handling of PATH has changed. My Python isn't on the path, perhaps that is it. A shebang line without "/env" doesn't check the path, right?Thank you for helping,Sibylle-- https://mail.python.org/mailman/listinfo/python-list
