国际象棋python

以下是一个简单的国际象棋Python程序的实现思路：

1. 定义棋盘大小、棋子类型和玩家类型等常量。
2. 使用二维列表board来表示棋盘，其中每个元素代表一个棋子。
3. 编写init_board()函数用于初始化棋盘。
4. 编写random_move()函数实现随机移动一个棋子的逻辑。
5. 编写play()函数实现游戏的主逻辑，包括初始化棋盘、随机移动棋子、判断游戏是否结束等。
6. 在主函数中调用play()函数开始游戏。

下面是一个简单的国际象棋Python程序的代码实现：

import random

# 定义棋盘大小、棋子类型和玩家类型等常量
BOARD_SIZE = 8
EMPTY = 0
PAWN = 1
ROOK = 2
KNIGHT = 3
BISHOP = 4
QUEEN = 5
KING = 6
BLACK = 0
WHITE = 1

# 使用二维列表board来表示棋盘，其中每个元素代表一个棋子
board = [[EMPTY for x in range(BOARD_SIZE)] for y in range(BOARD_SIZE)]

# 初始化棋盘
def init_board():
    for x in range(BOARD_SIZE):
        board[1][x] = PAWN + BLACK
        board[6][x] = PAWN + WHITE
    board[0][0] = ROOK + BLACK
    board[0][7] = ROOK + BLACK
    board[7][0] = ROOK + WHITE
    board[7][7] = ROOK + WHITE
    board[0][1] = KNIGHT + BLACK
    board[0][6] = KNIGHT + BLACK
    board[7][1] = KNIGHT + WHITE
    board[7][6] = KNIGHT + WHITE
    board[0][2] = BISHOP + BLACK
    board[0][5] = BISHOP + BLACK
    board[7][2] = BISHOP + WHITE
    board[7][5] = BISHOP + WHITE
    board[0][3] = QUEEN + BLACK
    board[7][3] = QUEEN + WHITE
    board[0][4] = KING + BLACK
    board[7][4] = KING + WHITE

# 随机移动一个棋子
def random_move():
    while True:
        x = random.randint(0, BOARD_SIZE - 1)
        y = random.randint(0, BOARD_SIZE - 1)
        if board[y][x] != EMPTY:
            break
    while True:
        dx = random.randint(-1, 1)
        dy = random.randint(-1, 1)
        if dx != 0 or dy != 0:
            break
    if x + dx < 0 or x + dx >= BOARD_SIZE or y + dy < 0 or y + dy >= BOARD_SIZE:
        return
    if board[y + dy][x + dx] == EMPTY:
        board[y + dy][x + dx] = board[y][x]
        board[y][x] = EMPTY

# 判断游戏是否结束
def is_game_over():
    black_king = False
    white_king = False
    for x in range(BOARD_SIZE):
        for y in range(BOARD_SIZE):
            if board[y][x] == KING + BLACK:
                black_king = True
            elif board[y][x] == KING + WHITE:
                white_king = True
    return not (black_king and white_king)

# 游戏主逻辑
def play():
    init_board()
    while not is_game_over():
        random_move()

# 调用play()函数开始游戏
play()
