Tic Tac Toe Game help with error.

So I've tested out the code for one of my assignments. I had to basically fill in board.py. When I try to run it, its giving me the following error:


How do I fix this? Is it because I am returning a copy of self._board when I am supposed to copy the whole instance of the Board class and return a Board object.

Yes, you've identified the problem. (how the heck would I know, I didn't change the program to make it functional) (It's a guess, the missing method is in that class.)

Use some function to clone that object.

I don't understand. Since a board object is basically a list. Why isn't it working? I tried to use a copy function but it still doesn't work. I only coded board class while the other classes came with the assignment. Would it be something wrong with def copy or would it be something wrong with def is_valid_move in board?

Try this in your python interpreter. Search the result for
is_valid_move
You won't find it because list objects haven't got is_valid_move methods nor data.
