使用python写一个爬取百度图片的爬虫

好的，以下是使用Python编写爬取百度图片的爬虫的代码：

import requests
import re

def get_img_urls(keyword, num):
    imgs = []
    for i in range(num):
        url = f'https://image.baidu.com/search/acjson?tn=resultjson_com&ipn=rj&word={keyword}&pn={i * 30}&rn=30'
        response = requests.get(url)
        img_urls = re.findall(r'"thumbURL":"(.*?)",', response.text)
        imgs += img_urls
    return imgs

def download_imgs(keyword, num):
    img_urls = get_img_urls(keyword, num)
    for i, url in enumerate(img_urls):
        response = requests.get(url)
        with open(f'{keyword}_{i}.jpg', 'wb') as f:
            f.write(response.content)
            print(f'Saved {keyword}_{i}.jpg')

if __name__ == '__main__':
    download_imgs('猫', 10)

这个爬虫可以通过搜索关键词来爬取百度图片，并下载到本地。
