Unable to retrieve feeds

[Luke Lee]

I'm using Python 3.6.6 on Mac OS and see the following error when running the realpython script:

Traceback (most recent call last):
  File "/Users/durden/.virtualenvs/reader/lib/python3.6/site-packages/feedparser.py", line 398, in __getattr__
    return self.__getitem__(key)
  File "/Users/durden/.virtualenvs/reader/lib/python3.6/site-packages/feedparser.py", line 356, in __getitem__
    return dict.__getitem__(self, key)
KeyError: 'title'

During handling of the above exception, another exception occurred:

I traced this down to some kind of SSL error so maybe I don't have something setup correctly? The error is a little confusing because the parsing doesn't return any feeds.

For example this line returns:

{'feed': {}, 'entries': [], 'bozo': 1, 'bozo_exception': URLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:841)'),)}

I'm able to read the XML feed correctly when pasting the url into Safari. I also saw a few related issues for feedparser since that's likely where the 'problem' is:

• kurtmckee/feedparser#84

I'm guessing it's something about my own SSL setup or the Python 3.6.6 I'm using not having the SSL module compiled correctly?

I can't remember for sure, but I think I'm using the Python directly from Python.org.

Found the solution! Apparently on OS X there's some certificate stuff that needs to be installed when using Python 3.6 from Python.org. See [this stack overflow post])https://stackoverflow.com/questions/49183801/ssl-certificate-verify-failed-with-urllib).

Essentially go to /Applications/Python 3.6 and run the Install Certificates.command

Ah, brilliant! Maybe we should add a small note about this in the Readme?
