Bij*_*jan 2 python attributeerror
我有一个返回网页标题的小脚本
title = BeautifulSoup(urllib2.urlopen(URL)).title.string
Run Code Online (Sandbox Code Playgroud)
但并非所有网站都指定<title>标签,在这种情况下我的脚本会返回
AttributeError: 'NoneType' object has no attribute 'string'

title如果网页上有标题,有没有办法让变量等于标题?
我经受过考验
if BeautifulSoup(urllib2.urlopen(url)).title.string.strip():
print BeautifulSoup(urllib2.urlopen(url)).title.string.strip()
else:
print url

但它仍然会引发 AttributeError 错误
