There are file system packages (with __init__.py) and PyPI packages. The former are an extremely poor version of Lisp packages, OCaml modules or C++ name spaces. The latter are distribution packages (even for distribution packages C++ has Conan etc.). PyPI packaging gets even worse than usual when attempting to distribute a file system package.
