beautiful soup库的小实践

首先得看下网页的特点，然后写爬虫实践一下。

import requests
import time
from bs4 import BeautifulSoup
import bs4

if __name__=="__main__":
	response=requests.get("http://www.zuihaodaxue.cn/zuihaodaxuepaiming2019.html")
	response.encoding="utf-8"
	soup=BeautifulSoup(response.text,"html.parser")
	soup.encode("utf-8")
	
	li=[]
	for tr in soup.find("tbody").children:
		if isinstance(tr,bs4.element.Tag):
			tds=tr("td")
			li.append([tds[0].string,tds[1].string,tds[2].string,tds[3].string])
	tplt = "{0:^10}\t{1:{4}^10}\t{2:^10}\t{3:^10}"
	print(tplt.format("排名","学校名称","城市","新生高考分数得分:",chr(12288)))
	for item in li[:100]:
		print(tplt.format(item[0],item[1],item[2],item[3],chr(12288)))
