如何获取根文件夹中的所有子文件夹名称并创建HTML内容？

import os

def get_subfolders(root_folder):
    subfolders = []
    
    for foldername, _, _ in os.walk(root_folder):
        if foldername != root_folder:
            subfolders.append(foldername)
    
    return subfolders

def create_html_content(subfolders):
    html_content = "<ul>\n"
    
    for folder in subfolders:
        html_content += f"<li><a href='{folder}'>{folder}</a></li>\n"
    
    html_content += "</ul>"
    
    return html_content

root_folder = "path/to/root/folder"
subfolders = get_subfolders(root_folder)
html_content = create_html_content(subfolders)

# 将HTML内容写入文件
with open("output.html", "w") as file:
    file.write(html_content)
