2048小游戏python

这是一个简单的2048小游戏的Python代码示例：

import random

# 定义游戏类
class Game2048:
    def __init__(self):
        self.grid = [[0] * 4 for _ in range(4)]
        self.score = 0
        self.add_random_num()
        self.add_random_num()

    # 随机在空白位置添加数字
    def add_random_num(self):
        empty_cells = [(i, j) for i in range(4) for j in range(4) if self.grid[i][j] == 0]
        if empty_cells:
            row, col = random.choice(empty_cells)
            self.grid[row][col] = 2 if random.random() < 0.9 else 4

    # 判断是否游戏结束
    def is_game_over(self):
        if not any(0 in row for row in self.grid):
            for i in range(4):
                for j in range(3):
                    if self.grid[i][j] == self.grid[i][j+1] or self.grid[j][i] == self.grid[j+1][i]:
                        return False
            return True
        return False

    # 反转矩阵
    def transpose(self):
        self.grid = [list(row) for row in zip(*self.grid)]

    # 矩阵向左移动
    def move_left(self):
        new_grid = []
        for row in self.grid:
            new_row = []
            last_num = 0
            for num in row:
                if num == 0:
                    continue
                if num == last_num:
                    new_row[-1] *= 2
                    self.score += new_row[-1]
                    last_num = 0
                else:
                    new_row.append(num)
                    last_num = num
            while len(new_row) < 4:
                new_row.append(0)
            new_grid.append(new_row)
        self.grid = new_grid

    # 矩阵向右移动
    def move_right(self):
        self.reverse()
        self.move_left()
        self.reverse()

    # 矩阵向上移动
    def move_up(self):
        self.transpose()
        self.move_left()
        self.transpose()

    # 矩阵向下移动
    def move_down(self):
        self.transpose()
        self.move_right()
        self.transpose()

    # 反转矩阵
    def reverse(self):
        self.grid = [row[::-1] for row in self.grid]

    # 打印游戏状态
    def print_grid(self):
        print("-" * 23)
        for row in self.grid:
            print("|", end="")
            for num in row:
                if num == 0:
                    print("{:^4}|".format(" "), end="")
                else:
                    print("{:^4}|".format(num), end="")
            print()
            print("-" * 23)
        print("Score:", self.score)

# 开始游戏
def start_game():
    game = Game2048()
    while True:
        game.print_grid()
        if game.is_game_over():
            print("Game Over!")
            break
        direction = input("Enter direction: ")
        if direction == "left":
            game.move_left()
        elif direction == "right":
            game.move_right()
        elif direction == "up":
            game.move_up()
        elif direction == "down":
            game.move_down()
        else:
            print("Invalid direction!")
            continue
        game.add_random_num()

if __name__ == "__main__":
    start_game()

这是一个简单的命令行游戏，可以通过输入left、right、up、down来控制方向。运行代码即可开始游戏。
