It doesn't? If I write this into a file (/tmp/test.py):

    #!/usr/bin/env python
    
    print("Hello, world!")

and mark it as executable (chmod +x /tmp/test.py), I can just execute it as /tmp/test.py like I would do with any bash file.

If you mean invocation as "execute a command that I'm passing", 'python -c' does exactly that.

Even as a complete shell it works including changing directories and using standard python to do file IO, though it won't execute any system executables and doesn't do piping like you'd like from a shell. It's not intended for that purpose so I can't really blame python for that.

I think that's what xonsh was made for? :)
