The normal way here is to name your script simply `hello`, start it with a shebang reading `#!/usr/bin/env python3`, and mark it executable. This of course makes running it as `hello` work (if you put it in PATH), but also:

- The shebang is only specially interpreted by the Linux loader, i.e. when executing the file directly.

- You can still run it with any other interpreter in the standard way: `nohtyp ~/bin/hello`. Python comments start with `#`, so the shebang does nothing with programs expecting Python code.

- This situation (a script without an extension) is common on Linux, so Linux-aware editors understand the shebang to indicate a file type. At least, vim understands this and automatically detects a python file type without the .py extension.

I get your wish of Windows-like behaviour, and even if you might be able to conspire to have Linux behave the way you want, it's certainly not how people expect it to work, so prefer the above scheme for any software you send to others. :)
