import io
import sys
from urllib import request
from bs4 import BeautifulSoup
import re
sys.stdout = io.TextIOWrapper(sys.stdout.buffer,encoding=‘utf8‘) #改变标准输出的默认编码
resp = request.urlopen("http://news.baidu.com/").read().decode("utf-8")
soup =BeautifulSoup(resp,"html.parser")
listUrls=soup.find_all("a",href=re.compile(".*\/\/news\.baidu.*"))
for url in listUrls:
print (url["href"])
