I have no idea what this is but I hope someone will answer this. I got this after merging 2 python modules together and I think that is the problem but I would like to know if there is a way to have 2 python modules in the same set of code. I'm trying to make a maze game with turtle and tkinter now but which do you think is best to use anyway?
