先看效果

1、环境准备

import requests
import re

下载requests库：

pip install requests

2、要爬取的网站

https://www.hippopx.com

3、程序源代码（可直接运行）

E:\test 需要在E盘下准备一个test 文件夹，当然，也可以自己更改存储路径

import requests
import rekeyword = input("请输入中文关键字：")
baseurl = 'https://www.hippopx.com/zh/search?q='+ str(keyword) +'&page='
downpage = input("请输入页数：")
downpage = int(downpage) + 2picList = []  # 图片列表
pattern =[]
num = 0for i in range(2,downpage):url = baseurl  + str(i)print(url)content = requests.get(url).content.decode('utf-8')pattern = re.compile('<link itemprop="thumbnail" href="(.+?)"').findall(content)# picList.append(pattern)picList = picList + patternprint(picList)
print(len(picList))# 下载图片
def dowmloadPicture():# 定义全局变量global numprint('找到的图片，即将开始下载图片...')for each in picList:print('正在下载第' + str(num + 1) + '张图片，图片地址:' + str(each))try:if each is not None:pic = requests.get(each, timeout=7)else:continueexcept BaseException:print('错误，当前图片无法下载')continueelse:# 保存路径string =  'E:\test\\' + str(num) + '.jpg'fp = open(string, 'wb')fp.write(pic.content)fp.close()num += 1# 调用下载图片方法
dowmloadPicture()
