Python 国际象棋引擎：如何用“#”替换输入方块上的棋子？

Question

当用户输入“a1”这样的坐标时，我想找到该方块上的棋子，并将其图标替换为“#”字符并渲染新棋盘。所以新棋盘中的车应该是“#”符号。

def find_piece(square, board):

            piece_idx = row.index(square)
            if idx < 2:  # If it's a black piece
                print(board[idx][piece_idx])  # Print the piece

            elif idx > 5:  # If it's a white piece
                print(board[idx][piece_idx])  # Print the piece
                return board[idx][piece_idx]
            else:
                return ""  # Empty square
    return ""

def board_display(board):
    for row in board:
        if "#" in row:
            # Replace "#" with the original pieces before displaying
            row = ["#" if square == "#" else square for square in row]
        print(" ".join(row))

def move(board):
    board_display(board)
    piece_initial = input("Move Piece On Square: ")
    piece = find_piece(piece_initial, board)
    if piece:
        print("Piece on square", piece_initial, ":", piece)
    piece_final = input(f"Move piece on square '{piece_initial}', to square: ")
    piece_2 = find_piece(piece_final, board)
    return board  # Return the updated board

# Define the initial state of the board
board = [
    piecesW,
    pawnsW,
    ["#" for _ in range(8)],
    ["#" for _ in range(8)],
    ["#" for _ in range(8)],
    ["#" for _ in range(8)],
    pawnsB,
    piecesB
]

while True:
    print("Current Board Setup: ")
    board = move(board)  # Update the board with the move

期望下次显示棋盘时，输入的方格上的棋子会被替换为“#”字符。现在什么也没有发生。

Answer 1

可能是由于下面的

if square in row

行：

def find_piece(square, board):
    for idx, row in enumerate(board):
        if square in row: # Square == "b2", but row is filled with "#" or piece symbols
            pass

假设我为

"b2"

输入了

square

值。由于您枚举的是仅包含

board

或

#

的

piece symbols

，因此

square in row

条件将始终为 false。
