That's a version of python that does not send SNI when opening TLS connections, so sites that don't have a dedicated IP address for the domain cannot support TLS with such clients, and most sites that do have a dedicated IP address won't support TLS "just because" (no SNI - get self signed dummy cert or closed connection). So the first thing I would have to do with such Python is monkeypatch ssl.
