https://github.com/vitepython/irc-clientA command line python irc client that takes user inputs in python 2.7
It's very basic but it's meant to only run on libraries that ship with standard python.
It only really needs one library "sockets".
You should be able to join as many channels as an irc server allows, a verbos mode that sends all data, an all Chan mode that parses channel and private messages into a easier to read format and a way to send private messages.
It's a proof of concept that you can have a basic irc client that should run on most os that ship with python. It also works on windows 7 to 10, haven't tested on a mac or smartphone yet.
