Optionaly a destination Path can be passed with the url using dest_folder argument. The output of the download method is a Path to the downloaded file.

async def download():
    q = 'japan history'
    result = await lg.search(q)
    download_location = []
    path = Path('Downloads')
    for item in result:
        file_path = await lg.download(result[item]['mirrors']['main'],
                                      dest_folder=path,
                                      progress=progress,
                                      progress_args=[
                                          result[item]['title']
                                      ])
        download_location.append(file_path)
