我怎么才能只列出目录名称，没有尾随的"/"？

import os

path = "/path/to/directory/"
directory_name = os.path.basename(path.rstrip('/'))
print(directory_name)

import re

path = "/path/to/directory/"
directory_name = re.search(r'([^/]+)/?$', path).group(1)
print(directory_name)

path="/path/to/directory/"
directory_name=$(basename "${path%/}")
echo $directory_name
