@jijosg Let's go! :D

Since i am a newbie to this, please let me know if this question is not relevant.
The original implementation of droplevel refers to _get_axis(axis) method to get the level names, are we supposed to implement that method as well? I couldnt find the existing implementation of such a function. @itholic if you could guide me forward that would be helpful.
Thanks

Hi, @jijosg .
I don't think we have to necessarily implement _get_axis for now.
Just feel free to implement method whatever you want, and I'll review it for you after then :D
