Python: importing a Python module without `.py` extension

import_path.py

from importlib.machinery import SourceFileLoader
from importlib.util import module_from_spec, spec_from_file_location
from pathlib import Path


def import_path(path: Path):
    module_name = path.stem.replace('-', '_')

    loader = SourceFileLoader(module_name, str(path))
    spec = spec_from_file_location(module_name, path, loader=loader)
    module = module_from_spec(spec)
    spec.loader.exec_module(module)

    return module


if __name__ == '__main__':
    mymodule_path = Path(__file__).parent / 'mymodule'
    mymodule = import_path(mymodule_path)

mymodule

print(f'{__name__} is loaded.')

The result output:

python import_path.py
# => mymodule is loaded.
