- I don't have a `py` command on my system; for purposes of this answer I assume it's an alias to the python executable.
- Running a script from a file is not quite the same as importing it. A script given on the command line doesn't know it's a package (`__package__` is not set). That's why relative imports don't work.
- What you probably want is to run it by module path, not filename. Assuming your top-level project directory is named `yourapp`:
- ```
- python3 -m yourapp.app
- ```
Run this from somewhere that `yourapp` is importable. Unless you've done something odd with PYTHONPATH, the parent of your top-level project directory should work.- (even better would be to make a setup.py and use it to pip-install the package; then your working directory won't matter. But you specified no structural changes, so.)
