如何访问嵌套数组中的特定值

def find_value(nested_array, target):
    for element in nested_array:
        if isinstance(element, list):
            result = find_value(element, target)
            if result is not None:
                return result
        elif element == target:
            return element
    return None

# 示例嵌套数组
nested_array = [1, 2, [3, 4, [5, 6, [7, 8]]], 9, [10, [11, 12]]]

# 访问特定值
target_value = 7
result = find_value(nested_array, target_value)

if result is not None:
    print("找到了目标值:", result)
else:
    print("未找到目标值")
