python批量下载狗狗图片

以下是使用Python批量下载狗狗图片的示例代码：

import requests
from lxml import etree

# 获取网页源码
def get_html(url):
    response = requests.get(url)
    html = response.text
    return html

# 解析网页源码，获取图片链接
def get_image_urls(html):
    tree = etree.HTML(html)
    image_urls = tree.xpath('//*[@id="container"]/div/div/a/img/@src2')
    return image_urls

# 下载图片
def download_images(image_urls):
    for i, url in enumerate(image_urls):
        response = requests.get(url)
        with open(f'dog_image_{i+1}.jpg', 'wb') as f:
            f.write(response.content)

# 主函数
def main():
    url = 'https://www.example.com'  # 替换为实际的网页链接
    html = get_html(url)
    image_urls = get_image_urls(html)
    download_images(image_urls)

if __name__ == '__main__':
    main()

请注意，上述代码中的`url`需要替换为实际的网页链接，以确保能够正确获取到狗狗图片的链接。另外，代码中使用了第三方库`requests`和`lxml`，请确保已经安装了这两个库。
