Thank you @zonca ! That link and its references helped me figure out that my Python had an old version of OpenSSL. I upgraded my python, and it is working perfectly!
Plus I got to learn a bit of the magic of IPython plugins [1], see more of how Gihub is so helpful [2].

So, re: your SSL connection error -- that looks like your version of Python was compiled against an outdated version of OpenSSL.
