代码来自2.2章节
运行后
警告的原因是没有指定显性的解析器，做一下修改，指定解析器
from urllib.request import urlopen
from bs4 import BeautifulSoup
html = urlopen("http://www.pythonscraping.com/pages/warandpeace.html")
bsObj = BeautifulSoup(html,"html.parser")
nameList = bsObj.findAll("span", {"class":"green"})
for name in nameList:
print(name.get_text())
现在在运行就没有警告了
