python使用线程池保存图片

以下是使用Python线程池保存图片的示例代码：

import requests
from concurrent.futures import ThreadPoolExecutor

def download_image(url):
    response = requests.get(url)
    filename = url.split("/")[-1]
    with open(filename, "wb") as f:
        f.write(response.content)
    print(f"{filename} saved successfully.")

def save_images_with_threadpool(urls, max_workers):
    with ThreadPoolExecutor(max_workers=max_workers) as executor:
        executor.map(download_image, urls)

# 示例
urls = ["https://example.com/image1.jpg", "https://example.com/image2.jpg", "https://example.com/image3.jpg"]
save_images_with_threadpool(urls, 10)

在这个示例中，我们使用了Python的requests库来下载图片，并使用了concurrent.futures模块中的ThreadPoolExecutor来创建线程池。download_image函数用于下载单个图片，save_images_with_threadpool函数用于将多个图片的下载任务提交给线程池。在示例中，我们将线程池的最大工作线程数设置为10。
