从URL下载图像并重命名

import urllib.request
import os

def download_image(url, new_name):
    try:
        # 打开URL链接并读取图像数据
        response = urllib.request.urlopen(url)
        image_data = response.read()
        
        # 创建新文件并写入图像数据
        with open(new_name, 'wb') as image_file:
            image_file.write(image_data)
        
        # 关闭文件和URL连接
        image_file.close()
        response.close()
        
        # 重命名文件
        os.rename(new_name, 'new_image.jpg')
        
        print("图像下载并重命名成功！")
    except Exception as e:
        print("图像下载并重命名失败：", str(e))

# 调用函数进行图像下载和重命名
