如何找到只有子目录名称的特定深子目录的路径？

import os

def find_subdirectory(root, target_directory):
    for dirpath, dirnames, filenames in os.walk(root):
        for dirname in dirnames:
            if dirname == target_directory:
                return os.path.join(dirpath, dirname)
    return None

root_directory = '/path/to/root/directory'
target_directory = 'subdirectory'

result = find_subdirectory(root_directory, target_directory)
if result:
    print("找到目录路径：", result)
else:
    print("未找到目录")
