python爬虫下载4k图片

Python爬虫是一种用于自动化获取网页数据的技术，可以用来下载4K图片。以下是一个简单的Python爬虫下载4K图片的示例代码：

import requests
import os

def download_4k_images(url, save_dir):
    response = requests.get(url)
    if response.status_code == 200:
        images = response.json()
        for image in images:
            image_url = image['url']
            image_name = image['name']
            save_path = os.path.join(save_dir, image_name)
            response = requests.get(image_url)
            if response.status_code == 200:
                with open(save_path, 'wb') as f:
                    f.write(response.content)
                print(f"Successfully downloaded {image_name}")
            else:
                print(f"Failed to download {image_name}")

# 示例使用Unsplash API获取4K图片
url = "https://api.unsplash.com/photos/random?query=4k&count=10"
save_dir = "path/to/save/directory"

download_4k_images(url, save_dir)

请注意，上述示例代码中使用了Unsplash API来获取4K图片，你需要替换`url`变量为你所需的图片源的API地址。同时，你需要将`save_dir`变量替换为你想要保存图片的目录路径。
