If you’re learning code, I suggest going with Java. It’s very easy to pick up and there’s a lot of features within the language.
Implementing a IRC bot in Java is really easy. There’s a framework called PircBot which does the whole IRC part of the bot - you just need to code the actions for it (bans, messages, etc.).
I’d really recommend taking that up instead - but if you’re just starting out, try something a bit simpler than going straight at the bot.
