我们可以将该类加载到 Python 3 解释器中,这样我们就可以交互式地使用它。为了做到这一点,将前面提到的类定义保存在一个名为first_class.py的文件中,然后运行python -i first_class.py命令。-i参数告诉 Python运行代码然后转到交互式解释器。以下解释器会话演示了与这个类的基本交互:...
Once PyRun_SimpleStringFlags() has created a module and a dictionary, it calls PyRun_StringFlags(), which creates a fake filename and then calls the Python parser to create an AST from the string and return a module, mod: C PyObject * PyRun_StringFlags(const char *str, int start,...
然后,如果我们未实现任何抽象方法,我们将收到一个 TypeError 异常,其中包含类似于 "Can't instantiate`` abstract class FrenchDeck2 with abstract methods __delitem__, insert" 的消息。这就是为什么我们必须实现 __delitem__ 和insert,即使我们的 FrenchDeck2 示例不需要这些行为:因为 MutableSequence ABC 要求...

To interact with the search service, you'll need to create an instance of the appropriate client class: SearchClient for searching indexed documents, SearchIndexClient for managing indexes, or SearchIndexerClient for crawling data sources and loading search documents into an index. To instantiate a ...
