When I was learning programming, my coding class used a Bukkit plugin that connected to Python. I can't remember what it was called, but that was for Minecraft 1.7.10. Not sure if you were wanting Python specifically, but KubeJS lets you use JavaScript for mods. I think there's also a clojure integration.
