从Python 2.6开始,通过__future__模块引入了后向移植机制,使我们可以在Python 2中限制只使用print函数。基于以上列出的各种原因,更重要的为了你的程序能够顺利从Python 2过渡到Python 3,应该优先使用函数版本的print。 不良风格: 1printl,'foo',__name__ 地道Python: 1from__future__importprint_function2print(l...
In data-oriented programming, however, you don't get this conceptual model, so you're more likely to have a bounce function that will throw an error if you send it anything other than a ball. Another example of working within conceptual models is the use of “object” in object-oriented...
这个类必须继承unittest.TestCase类,这样python才知道如何运行编写的测试。NameTestCase只包含一个方法,用于测试get_formatted_name()的一个方面。运行test_name_function.py时,所有以test_开头的方法都将自动运行。 self.assertEqual()断言方法:unittest类最有用的功能之一,断言方法核实得到的结果是否与期望的结果一致...
In C++, a class that contains some data type T would be templated asclass C<T>. In Python, the class we be named simplyclass C. In C++, a function which operates polymorphically over a type T would be templated astemplate <typename T> f(...), so that the functions body would be...

Python's len and str come in handy a lot of times, and they're convenient to use because they're free functions (that is, not member functions). Fortunately, C++ has its own set of free functions that are quite helpful:size(v): It returns the unsigned size of vv, and does the sam...
