Python puts source code in a directory with the package's name. That's why the source code is really under `repo_root/package/`, not under `repo_root/` as you seem to imply. It's just that it's not called `src/`, but `package/` in Python (but that's configurable!). So if you have a project called "splitter", your source code really lives under `splitter/splitter/`. I would agree that seems a bit redundant and `splitter/src` look better, but the source code is not in the project root.
