3.2 ArxDbg ArxDbg 是 ObjectARXSDK中包含多年的示例项目的名称。它的主要目的是演示如何使用 ObjectARX API,但它本身就是一个完全独立的实用程序。ObjectARX 程序员经常在开发期间使用此实用程序来测试和执行他们的应用程序代码。更多详见:[ObjectARX] ArxDbg介绍、自动加载及其下载。 ArxDbg • ...
To get the most out of this tutorial, you should know the basics of object-oriented programming, classes, and decorators in Python.Get Your Code: Click here to download the free sample code that shows you how to use Python’s property() to add managed attributes to your classes....
You started this tutorial by looking closer at functions, and particularly how you can define them inside other functions and pass them around just like any other Python object. Then you learned about decorators and how to write them such that: They can be reused. They can decorate functions ...

One of the first things that should stick out is that we’re using themock.patchmethod decorator to mock an object located atmymodule.os, and injecting that mock into our test case method. Wouldn’t it make more sense to just mockositself, rather than the reference to it atmymodule.os...
return self.name == o.name >>> s = set() >>> s.add(User("tom")) >>> s.add(User("tom")) >>> s set([<__main__.User object at 0x10a48d150>]) 数据结构很重要,这⼏几个内置类型并不⾜足以完成全部⼯工作.像 C,数据结构,常⽤用算法这类基础是 每个程序开发⼈人员都应该...
