抱歉塞了这么多元素

无论如何，我想过滤掉字典中键值中的元组我想删除包含小于 0 或大于 20 的数字的元组，如果您想进一步详细说明，我会添加它但是我想我解释得非常准确。

例如预期的输出：

{(0, 0): [(1, 0), (0, 1)], (0, 1): [(1, 1), (0, 0), (0, 2)], (19, 6): [(18, 6), (19, 5), (19, 7)], (19, 7): [(18, 7), (19, 6), (19, 8)]..}

现在的输出：

{(0, 0): [(1, 0), (-1, 0), (0, -1), (0, 1)], (0, 1): [(1, 1), (-1, 1), (0, 0), (0, 2)], (19, 6): [(20, 6), (18, 6), (19, 5), (19, 7)], (19, 7): [(20, 7), (18, 7), (19, 6), (19, 8)]..}

希望可以理解！
