AI代码解释 defperson_decoder(obj):if"name"inobjand"age"inobj:returnPerson(name=obj["name"],age=obj["age"])returnobj# 反序列化JSON字符串loaded_person=json.loads(json_string_custom,object_hook=person_decoder)print(loaded_person.__dict__) 这样,我们就实现了自定义类的序列化与反序列化,使得JS...
Python 单元测试详解 本文直接从常用的Python单元测试框架出发,分别对几种框架进行了简单的介绍和小结,然后介绍了 Mock 的框架,以及测试报告生成方式,并以具体代码示例进行说明,最后列举了一些常见问题。 一、常用 Python 单测框架 若你不想安装或不允许第三方库,那么unittest是最好也是唯一的选择。反之,pytest无疑是...
文件对象模型(Document Object Model,简称DOM),是W3C组织推荐的处理可扩展置标语言的标准编程接口。一个 DOM 的解析器在解析一个XML文档时,一次性读取整个文档,把文档中所有元素保存在内存中的一个树结构里,之后你可以利用DOM 提供的不同的函数来读取或修改文档的内容和结构,也可以把修改过的内容写入xml文件。python...
inspect.isdatadescriptor(object) Return True if the object is a data descriptor. Data descriptors have a __set__ or a __delete__ method. Examples are properties (defined in Python), getsets, and members. The latter two are defined in C and there are more specific tests available for th...
