ssl ,urllib3,requests .exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:548)

I'm developing an application that collects information from YouTube via the YouTube APIv3. I'm using yapi package from github. I was working in Python2.7 and it worked fine.

But when I upgraded to Python 3.3 it suddenly gave me a certificate error.

Input

import yapiYoutube = yapi.YoutubeAPI('API KEY')Results = Youtube.general_search('keyword', max_results=10)print(Results)

Output

I had to change to Python 3.4 to try support other functions that I was using that only supported 3 and up.
