用Python语言编写爬取百度图片中猫和狗的图片各100张，将图片存入相应文件夹

好的，以下是Python代码：

import os
import requests
from bs4 import BeautifulSoup

def download_images(url, folder, num):
    if not os.path.exists(folder):
        os.mkdir(folder)
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    items = soup.find_all('img')
    count = 0
    for item in items:
        if 'src' in item.attrs:
            if 'jpg' in item['src'] or 'png' in item['src']:
                img_url = item['src']
                response = requests.get(img_url)
                if response.status_code == 200:
                    file_path = os.path.join(folder, f'{count}.jpg')
                    with open(file_path, 'wb') as f:
                        f.write(response.content)
                        count += 1
                    if count == num:
                        break

if __name__ == '__main__':
    cat_url = 'https://www.baidu.com/s?tn=80035161_1_dg&ie=utf-8&word=%E7%8C%AB'
    dog_url = 'https://www.baidu.com/s?tn=80035161_1_dg&ie=utf-8&word=%E7%8B%97'
    cat_folder = 'cat'
    dog_folder = 'dog'
    num = 100
    download_images(cat_url, cat_folder, num)
    download_images(dog_url, dog_folder, num)

在脚本中，我们首先定义`download_images`函数，该函数使用`requests`和`BeautifulSoup`库来解析网页和获取图片。然后，我们定义了两个URL：一个是用于猫的图片搜索结果的URL，另一个是用于狗的图片搜索结果的URL。我们还定义了两个文件夹，以存储下载的图像。我们使用`download_images`函数从每个URL下载100张图像，并将它们存储在相应的文件夹中。
