The local parameter "board" shades the class with the same name, > size[0],size[1]=size[1],size[0] > new=board(size) so here you are not making a new board instance but instead trying to call the board parameter which is a list. To fix this problem you have to rename the parameter or the class. I recommend that you rename the class to Board (by convention class names start with an uppercase letter). As to the parameter board, you actually don't need it at all -- you can instead make the board attribute of the new Board instance a rotated version of self.board. (There are more bugs in your code, but I suggest you tackle them one at a time.
