This is my most recent rendition of the code. It still needs to be
improved. Below I am answering some questions that were posed. Also I
think my code is currently wrong because I think the print_by functions
are both printing the list the same way. Tomorrow I will fix this and
improve the code
Thanks, definitely adding this concept into my code. And re-writing. I
originally hard coded everything just to get it working... but
obviously, it would have been more time efficient to have thought in
these terms from the beginning. Hopefully I can learn to write code more
like this to begin

What are the _operations_ you want to support? C

Here is a condensed version of all of the applicable code but with out
Linked List filled in, as I am preparing to re-write it.
class GameTile():
def __init__(self, id, **kwargs):
self.id = id
class GameGrid():
def __init__(self, **kwargs):
self.cols = 8
self.row
OK thanks for the rapid response, I will start rewriting the functions
in this way now, and will come back with what I wind up with.
Also Merry Christmas!

I wrote some code recently to make a linked list of Nodes for a 2d
graph, so it consists of rows and columns. Now I wanted to make the code
support being doubly linked, forwards and backwards. The difficult part
of this is that the links are per row and per column. But the code I
