Python urllib2读取网页打不开报urllib2.URLError错误，,使用Python读取某个

使用Python读取某个网页的数据，如果网页打不开，就会报错
代码如下

url = "http://www.testxxxxxxxxxxx.com/";urllib2.urlopen(url).read().decode('utf-8','ignore')

报错如下

urllib2.URLError: <urlopen error [Errno 11004] getaddrinfo failed>

刚刚试了下，这样没法捕获错误：

try:    response= urllib2.urlopen(url)    data    = response.read().decode('utf-8','ignore')except urllib2.HTTPError,e:    print e.code    return ""return data

try:    response= urllib2.urlopen(url)    data    = response.read().decode('utf-8','ignore')except:    return ""return data
