如何删除文档目录的内容(而不是文档目录本身)？

import os
import shutil

def delete_directory_contents(dir_path):
    for filename in os.listdir(dir_path):
        file_path = os.path.join(dir_path, filename)
        try:
            if os.path.isfile(file_path) or os.path.islink(file_path):
                os.unlink(file_path)
            elif os.path.isdir(file_path):
                shutil.rmtree(file_path)
        except Exception as e:
            print(f'Failed to delete {file_path}. Reason: {e}')

# 使用示例
delete_directory_contents('/path/to/directory')

import os

def change_file_permissions(file_path):
    try:
        os.chmod(file_path, 0o755)  # 更改文件权限为可读、可写、可执行
    except Exception as e:
        print(f'Failed to change permissions for {file_path}. Reason: {e}')

# 使用示例
change_file_permissions('/path/to/file')
