2048python简易版小游戏

以下是一个简单的2048 Python小游戏的实现，你可以参考一下：

import random

# 初始化游戏面板
def init_board(n):
    board = [[0] * n for i in range(n)]
    return board

# 在游戏面板上随机生成一个新的数字
def add_new_num(board):
    n = len(board)
    empty_cells = []
    for i in range(n):
        for j in range(n):
            if board[i][j] == 0:
                empty_cells.append((i, j))
    if empty_cells:
        i, j = random.choice(empty_cells)
        board[i][j] = 2 if random.random() < 0.9 else 4

# 判断游戏是否结束
def is_game_over(board):
    n = len(board)
    for i in range(n):
        for j in range(n):
            if board[i][j] == 0:
                return False
            if i < n - 1 and board[i][j] == board[i+1][j]:
                return False
            if j < n - 1 and board[i][j] == board[i][j+1]:
                return False
    return True

# 向左移动游戏面板
