pathlib.Path().glob() and multiple file extension

I need to specify multiple file extensions like pathlib.Path(temp_folder).glob('*.xls', '*.txt'):

How I can do it?

https://docs.python.org/dev/library/pathlib.html#pathlib.Path.glob

If you need to use pathlib.Path.glob()

from pathlib import Path
def get_files(extensions):
    all_files = []
    for ext in extensions:
        all_files.extend(Path('.').glob(ext))
    return all_files

files = get_files(('*.txt', '*.py', '*.cfg'))
