I realize this response is a few years too late, but I also ran into the same problem, and didn't want to depend on libcurl being installed on a machine where I ran this. Hopefully, this will be useful to those who find this post in the future.

The problem is that httplib.HTTPSConnection.connect doesn't have a way to specify SSL context or version. You can overwrite this function before you hit the meat of your script for a quick solution.

An important consideration is that this workaround, as discussed above, will not verify the validity of the server's certificate.

import httplib
import socket
import ssl
import urllib2

def connect(self):
    "Connect to a host on a given (SSL) port."

    sock = socket.create_connection((self.host, self.port),
                                    self.timeout, self.source_address)
    if self._tunnel_host:
        self.sock = sock
        self._tunnel()

    self.sock = ssl.wrap_socket(sock, self.key_file, self.cert_file, ssl_version=ssl.PROTOCOL_TLSv1)

httplib.HTTPSConnection.connect = connect

opener = urllib2.build_opener()
f = opener.open('https://www.google.com/')

*Note: this alternate connect() function was copy/pasted from httplib.py, and simply modified to specify the ssl_version in the wrap_socket() call
