我正在使用google-python课程进行练习。但是，我遇到了urllib问题。这是简化的代码：

import urllib
url = 'http://www.google.com'
ufile=urllib.urlopen(url)

这段代码实际上有效，但是如果我将网址更改为其他网址，例如：

url = 'https://developers.google.com/edu/python/utilities#exceptions'

它将引发错误：

IOError: [Errno socket error] [SSL: CERTIFICATE_VERIFY_FAILED]   certificate verify failed (_ssl.c:590)

完整的错误信息如下：
