Python动态创建目录，然后在目录中添加图像不起作用

import os
import shutil

def create_directory(directory_path):
    if not os.path.exists(directory_path):
        os.makedirs(directory_path)
        os.chmod(directory_path, 0o777)  # 设置目录权限为777

def add_image_to_directory(directory_path, image_path):
    if os.path.exists(directory_path):
        shutil.copy(image_path, directory_path)
        print("图像添加成功！")
    else:
        print("目录不存在！")

# 示例用法
directory_path = "path/to/directory"
image_path = "path/to/image.jpg"

create_directory(directory_path)
add_image_to_directory(directory_path, image_path)
