爬妹子图（爬图片的普适性）

import requests

import urllib.request

from bs4 import BeautifulSoup

header = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36"}

url="https://www.meizitu.com/a/5521.html"

res=requests.get(url,headers=header)

res.encoding = res.apparent_encoding

html=res.text

soup = BeautifulSoup(html, 'html.parser')

meizi=soup.find_all("img")

x=1

for i in meizi:

    imgsrc=i.get('src')

    print(imgsrc)

    urllib.request.urlretrieve(imgsrc,  './妹子/%s.jpg' %x)

    x=x+1

把url="https://www.zhihu.com/question/302378021/answer/557792503"

for i in meizi[1::2]:   [1::2]代表从第二个开始 隔一个隔一个取出直到最后

两句改了可以爬知乎的表情包 具有一定的普适性
