能否帮我写一段爬取百度图片的程序

当然可以！你可以使用Python的第三方库requests和BeautifulSoup来爬取百度图片。以下是一个简单的代码段：

import requests
from bs4 import BeautifulSoup

url = 'https://image.baidu.com/search/index?tn=baiduimage&word=美女'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
imgs = soup.find_all('img')

for img in imgs:
    print(img['src'])

上面这段代码会根据关键词“美女”在百度图片中进行搜索，并输出所有搜索结果中的图片链接。你可以进一步完善这个代码，将获取到的图片链接下载到本地，或者使用其他第三方库进行存储和处理。

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。

帮我写一个爬取百度图片的python爬虫

以下是一个基本的爬取百度图片的Python爬虫：

import requests
import os

def download_pic(pic_url, save_path):
    response = requests.get(pic_url)
    with open(save_path, 'wb') as f:
        f.write(response.content)

def search_and_download(keyword, download_path):
    url = 'https://image.baidu.com/search/index?tn=baiduimage&word={}'.format(keyword)
    response = requests.get(url)
    pic_urls = response.json()['data']
    for i, pic_info in enumerate(pic_urls):
        pic_url = pic_info['large_image_url']
        save_path = os.path.join(download_path, '{}.jpg'.format(i))
        download_pic(pic_url, save_path)

if __name__ == '__main__':
    keyword = '猫'
    download_path = './download'
    if not os.path.exists(download_path):
        os.mkdir(download_path)
    search_and_download(keyword, download_path)

该爬虫首先构造了一个百度图片搜索的URL，然后发送请求获取搜索结果，解析出每张图片的URL，并下载保存到本地。需要注意的是，由于百度图片的URL可能会变化，因此该爬虫并不一定能够一直正常工作。
