2048python编程代码

2048是一个流行的数字游戏，下面是一个使用Python编写的简单的2048游戏代码：

# 导入所需库
import curses
from random import randrange, choice
from collections import defaultdict

# 定义游戏主函数
def main(stdscr):
    # 设置键位操作
    keys = {
        'W': [-1, 0], 'w': [-1, 0],
        'S': [1, 0], 's': [1, 0],
        'A': [0, -1], 'a': [0, -1],
        'D': [0, 1], 'd': [0, 1],
    }

    # 定义游戏盘面大小和终止条件
    n = 4
    win_value = 2048

    # 初始化游戏盘面
    def init():
        # 创建一个2D矩阵，并将每个元素初始化为0
        return [[0 for _ in range(n)] for _ in range(n)]
    # 随机生成一个新数字
    def generate():
        # 80%的概率生成2，20%的概率生成4
        return 2 if randrange(100) > 80 else 4

    # 绘制游戏界面
    def draw():
        stdscr.clear()
        for row in game_board:
            stdscr.addstr(' '.join(map(str, row)) + '\n')
