当目录操作delete失败时，如何执行资源？

import shutil
import os

def delete_directory(path):
    try:
        shutil.rmtree(path)
        print(f"Directory {path} deleted successfully.")
    except PermissionError as e:
        print(f"Permission denied: {e}. Trying to change permissions...")
        os.chmod(path, 0o777)  # Change permissions to read-write-execute for all users
        try:
            shutil.rmtree(path)
            print(f"Directory {path} deleted successfully after changing permissions.")
        except Exception as e:
            print(f"Failed to delete directory {path}: {e}")
    except OSError as e:
        print(f"OS error occurred: {e}")

# Example usage
delete_directory("/path/to/directory")
