如何使用python从mac上的光盘中完全删除文件？

import os
import shutil

disk_path = "/Volumes/光盘名称"

def delete_files(path):
    for root, dirs, files in os.walk(path):
        for file in files:
            file_path = os.path.join(root, file)
            os.remove(file_path)
        for dir in dirs:
            dir_path = os.path.join(root, dir)
            shutil.rmtree(dir_path)

delete_files(disk_path)

import os
import shutil

disk_path = "/Volumes/光盘名称"

def delete_files(path):
    for root, dirs, files in os.walk(path):
        for file in files:
            file_path = os.path.join(root, file)
            os.remove(file_path)
        for dir in dirs:
            dir_path = os.path.join(root, dir)
            shutil.rmtree(dir_path)

delete_files(disk_path)
