How to use the watchgod.PythonWatcher function in watchgod

def test_python(tmpdir):
    mktree(tmpdir, tree)

    watcher = PythonWatcher(str(tmpdir))

    sleep(0.01)
    tmpdir.join('foo/spam.py').write('xxx')
    tmpdir.join('foo/bar.txt').write('xxx')

    assert watcher.check() == {(Change.modified, str(tmpdir.join('foo/spam.py')))}

async def thread_proc(self):
        from pycrunch.pipeline.file_modification_task import FileModifiedNotificationTask

        logger.debug('thread_proc')
        logger.debug(f'files {self.files}')

        logger.debug(f'files {self.files}')

        path = Path('.').absolute()
        print('watching this:...')
        print(path)
        async for changes in awatch(path, watcher_cls=PythonWatcher):
