python urllib got [Errno socket error]

Question

I'm doing practice with the google-python course. However, I got problem with the urllib. Here is the simplified code:

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

This code actually works, but if I change the url to some other ones, like:

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

It will raise the error:

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

The full error information is as follows:

Traceback (most recent call last):

Python is much more strict with ssl currently than it has been before. You can temporarily bypass the ssl verification. Take a look at this post. Of course this might not be a permanent solution but if You have no access to configure developers.google.com certs, that might be the best you can do.

1 check the SSL version

2 to ensure that the bottom of the socket module is to support the SSL compile mode, that is, when the SSL compiler option is open.

3 port error, check it

Thank you very much for your quick reply. I know little about SSL and socket, so if you don't mind, could you briefly show me how to do this or do you have any recommended reading for these? Thanks again. – jren Mar 21 '16 at 08:17
