Alter my code in python to work for a specific question

an AVL is a balanced binary search tree, I need this to be altered so it works as a priority tree, there are instructions on this on a webpage that I will send you if you are confident you can do this, you pretty much only need to alter one method in my AVL class and that's it, I'm paying no more than $15 for this since this is easy introductory python 3.x, I will send you the info if you are interested
