openssl and Python

Hello everyone, In my free time I've been fooling around with a few python libraries and openssl to create web scanning tools for my fellow system engineers. The main premise of the tools is that it scans an entire network for hosts listening on 443, 8443, etc and tries to establish a connection using a bunch of different protocol/cipher combinations. The results is a list of servers on that network and the various protocols, ciphers it supports. This allow admin's to quickly scan their environment and make changes.

One of the main hurtles I'm having is that most modern Linux distro's ship with a pretty up-to-date version of openssl which by default doesn't support SSLv2 or SSLv3. This of course is better for security but bad for me because I want to TRY and make a connection using both of those protocols.

WHAT I'VE TRIED: I installed a static version of openssl that is used in TestSSL(https://testssl.sh/) which showed promise because I was then able to establish a connection with those servers using just the openssl command line utility ("openssl s_client -connect .... etc"). However, in python, using the "ssl" and "pyOpenSSL" library, I get errors (saying it can't support those protocols)

MY QUESTION: How does the ssl library or the pyopenssl library "interface" with openssl? I suspect that python is "talking" with openssl in other ways and therefore still using the newer version of openssl and not the TestSSL openssl that I statically built.

Thanks for the insight every one!
