2048python

2048 是一个非常流行的数字游戏，我们可以使用 Python 来实现它。下面是一个示例代码：

import random

# 初始化游戏棋盘
def start_game():
    board = [[0] * 4 for _ in range(4)]
    board = add_new_tile(board)
    board = add_new_tile(board)
    return board

# 打印游戏棋盘
def print_board(board):
    for row in board:
        print('\t'.join(map(str, row)))

# 在空白位置随机添加一个新的数字（2 或 4）
def add_new_tile(board):
    r, c = random.choice([(i, j) for i in range(4) for j in range(4) if board[i][j] == 0])
    board[r][c] = random.choice([2, 4])
    return board

# 检查游戏是否结束
def is_game_over(board):
    for row in board:
        if 0 in row:
            return False
        for i in range(3):
            if row[i] == row[i + 1]:
                return False
    for j in range(4):
        for i in range(3):
            if board[i][j] == board[i + 1][j]:
                return False
    return True

# 处理向左移动操作
def move_left(board):
    new_board = []
    for row in board:
        new_row = [val for val in row if val != 0]
        while len(new_row) < 4:
            new_row.append(0)
        for i in range(len(new_row) - 1):
            if new_row[i] == new_row[i + 1]:
                new_row[i] *= 2
                new_row[i + 1] = 0
        new_row = [val for val in new_row if val != 0]
        while len(new_row) < 4:
            new_row.append(0)
        new_board.append(new_row)
    return new_board

# 处理游戏操作
def move(board, direction):
    if direction == 'up':
        board = rotate_left(board)
        board = move_left(board)
        board = rotate_right(board)
    elif direction == 'down':
        board = rotate_right(board)
        board = move_left(board)
        board = rotate_left(board)
    elif direction == 'left':
        board = move_left(board)
    elif direction == 'right':
        board = rotate_right(board)
        board = rotate_right(board)
        board = move_left(board)
        board = rotate_right(board)
        board = rotate_right(board)
    return board

# 将棋盘向左旋转90度
def rotate_left(board):
    return [list(row[::-1]) for row in zip(*board)]

# 将棋盘向右旋转90度
def rotate_right(board):
    return [list(row) for row in zip(*board[::-1])]

# 游戏主循环
def main():
    board = start_game()
    print("Welcome to 2048!")
    print_board(board)
    while not is_game_over(board):
        direction = input("Enter your move (up/down/left/right): ")
        board = move(board, direction.lower())
        board = add_new_tile(board)
        print_board(board)
    print("Game Over!")

if __name__ == "__main__":
    main()

这段代码实现了一个简化版的 2048 游戏。你可以运行它并根据提示输入移动方向（上、下、左、右），然后在命令行中看到游戏的进展。当游戏结束时，会显示 "Game Over!"。希望这个例子对你有帮助！
