最近有小伙伴留言说自己平时比较喜欢保存百度上的图片，但是每次都一张一张的下载比较麻烦，想写代码自动下载；对于这个功能的实现的话，其实还是比较简单的。接下来蜜蜂就在代码中用正则实现这一需求。

1.首先，百度图片都需要用关键字搜索，比如说下图搜索”小姐姐“,就会看到很多小姐姐的图片。

python代码实现输入关键字下载图片_下载图片

2.代码部分：

import os
import re
import requests
def baidupicture(word):
    url=f'https://m.baidu.com/sf/vsearch?pd=image_content&word={word}&tn=vsearch&atn=page'

if __name__ == '__main__':
    word=input("请输入关键字:")
    baidupicture(word)

3.运行效果：

python代码实现输入关键字下载图片_关键字_02

图片：

python代码实现输入关键字下载图片_下载图片_03

4.同理，我们在运行的时候输入其他关键字也是一样的，如”漂亮的星空“

运行效果：

python代码实现输入关键字下载图片_爬虫_04

图片：

python代码实现输入关键字下载图片_爬虫_05
