我想在IBMwatson中显示python字典的一些上下文作为输出。例如，如果我有一本像这样的字典
{'author': 'Bloomberg News',
'title': 'India Crisis Worsens; N.Y. Deaths at 5-Month Low: Virus Update',
'description': 'India Crisis Worsens; N.Y. Deaths at 5-Month Low: Virus Update',
'url': 'https://www.bloombergquint.com/business/n-y-deaths-at-5-month-low-india-crisis-deepens-virus-update',
'source': 'Bloomberg | Latest And Live Business',
'image': None,
'category': 'business',
'language': 'en',
'country': 'us',
'published_at': '2021-05-02T04:48:26+00:00'}
然后要在IBM Watson Assistant中打印标题作为输出，我们需要这样写：
<?data['title']?>
这将产生以下产出：印度危机；纽约州死亡人数创5个月新低：病毒更新
现在，如果我有一本这样的字典：

然后如何用XML打印每篇文章的标题名称(正如我上面提到的语法(。
Desired Output:

查看您的需求，您可能希望查看可应用于数据的方法列表，请参阅Watson Assistant文档中的表达式语言方法。使用这些方法，您可能能够将数组操作为所需的输出
或者，您可以调用一个外部RESTapi来处理数据并返回所需的输出。这个外部api可以是一个IBMCloud函数
最后也是最简单的一点是，您可以拥有一个对话框节点，该节点具有与答案数组(python中的列表/目录(大小相对应的多个响应条件。然而，这种方法通常只适用于小的答案组，并且数组/列表/目录的最大大小是已知的。
