表示非方形棋盘游戏的数据结构可以使用二维数组或链表。

一、使用二维数组

class Chessboard:
    def __init__(self, rows, cols):
        self.rows = rows
        self.cols = cols
        self.board = [[' ' for _ in range(cols)] for _ in range(rows)]

    def print_board(self):
        for row in self.board:
            print('|'.join(row))
    
    def update_cell(self, row, col, value):
        self.board[row][col] = value

# 示例用法
chessboard = Chessboard(5, 7)
chessboard.update_cell(2, 3, 'X')
chessboard.update_cell(4, 6, 'O')
chessboard.print_board()

二、使用链表

class Cell:
    def __init__(self, row, col, value):
        self.row = row
        self.col = col
        self.value = value
        self.next = None

class Chessboard:
    def __init__(self):
        self.head = None

    def print_board(self):
        current = self.head
        while current:
            print(f"({current.row}, {current.col}): {current.value}")
            current = current.next
    
    def update_cell(self, row, col, value):
        if not self.head:
            self.head = Cell(row, col, value)
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = Cell(row, col, value)

# 示例用法
chessboard = Chessboard()
chessboard.update_cell(2, 3, 'X')
chessboard.update_cell(4, 6, 'O')
chessboard.print_board()

以上是两种表示非方形棋盘游戏的数据结构的解决方法，你可以根据自己的需求选择其中一种来使用。
