前言：做核心算法之前我们可以玩一玩这个小游戏来了解一下规则。2048在线试玩

代码案例：

# 2048小游戏

# 1.将列表中零移动到列表的末尾
def move_zeroes():
    x = 0
    for i in range(len(list_nums)):
        if list_nums[i] != 0:

            x += 1


# 2.将相邻相等的合并
def merge():
    move_zeroes()

        if list_nums[i] == list_nums[i + 1]:
            list_nums[i] *= 2
            list_nums.pop(i + 1)
            list_nums.append(0)


# 向左移动
