能否帮我写一段爬取百度图片的程序，并加上一些反反爬措施

当然可以，以下是一个简单的Python程序，使用BeautifulSoup和requests库来爬取百度图片，并加上了一些基本的反反爬措施：

import requests
from bs4 import BeautifulSoup
import os

base_url = 'https://image.baidu.com/search/index?tn=baiduimage&word='
keyword = 'puppy'

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}

def get_page_urls(url):
    html = requests.get(url, headers=headers).text
    soup = BeautifulSoup(html, 'lxml')
    img_urls = []
    for img in soup.find_all('img', class_='main_img'):
        img_urls.append(img['src'])
    return img_urls
  
def download_imgs(img_urls, folder):
    if not os.path.exists(folder):
        os.makedirs(folder)
    for i, img_url in enumerate(img_urls):
        print('Downloading {}/{}...'.format(i + 1, len(img_urls)))
        try:
            response = requests.get(img_url, headers=headers, timeout=10)
            with open(folder + '/{}.jpg'.format(i), 'wb') as f:
                f.write(response.content)
        except:
            print('Fail to download {}...'.format(img_url))

def main():
    url = base_url + keyword
    img_urls = get_page_urls(url)
    download_imgs(img_urls, keyword)

if __name__ == '__main__':
    main()

注意：此程序仅供学习参考，实际应用中需要更加严格的反爬措施和代码优化。
