Python：如何添加两个大型掩码数组并保留它们的值（即掩码+；value=value）？

我想以这样的方式组合两个掩蔽数组

array_one      = [1,    mask,   mask]

array_two      = [mask, 2,      mask]

combined_array = [1,    2,      mask]

请注意，我有巨大的二维阵列

代码：

面具 大西洋面具 我也试过类似的东西

Atl = set(Atl)

SO = set.union(Atl,SO)

试试这个：

combined_array = list(set(array_one+array_two))

请共享您的代码，并指定代码的哪一部分不起作用。请编辑问题，而不是将未模拟的代码作为注释发布

Atl = set(Atl)

SO = set.union(Atl,SO)

combined_array = list(set(array_one+array_two))

array_one = [1, None, None, 3]
array_two = [None, 2, None, 4]


def combine(primary_array, secondary_array):
    """
    Arrays must be of equal length, primary overwrites secondary
    :param primary_array: [1, None, None, 3]
    :param secondary_array: [None, 2, None, 4]
    :return: [1, 2, None, 3]
    """
    result = []
    for x, y in zip(primary_array, secondary_array):
        if x is None and y is None:
            result.append(None)
        elif isinstance(x, (int, float)):
            result.append(x)
        elif isinstance(y, (int, float)):
            result.append(y)
        else:
            # Ignore if both x and y != int or float
            pass
    return result


print(combine(array_one, array_two))
