我还使用pytest为一些较大的示例编写了单元测试——我发现它比标准库中的unittest模块更易于使用且功能更强大。你会发现,通过在操作系统的命令行 shell 中键入python3 -m doctest example_script.py或pytest,可以验证本书中大多数代码的正确性。示例代码仓库根目录下的pytest.ini配置确保 doctests 被pytest命令收集和...

Most wxPython code will require you to subclass the wx.Frame and other widgets so that you can get the full power of the toolkit. Let’s take a moment and rewrite your code as a class: Python import wx class MyFrame(wx.Frame): def __init__(self): super().__init__(parent=...
The ability of a class to inherit the properties of another class is known as inheritance. The class that inherits the properties is usually called a subclass or derived class. The class that is being inherited is known as a superclass or a base class. Inheritance provides code reusability, ...

嵌套模块在 Python 中并不常见——至少我之前没有见过像module.class.subclass.function这样的东西——可读性不好。虽然在另一个子模块中构建子模块可能会减少代码行数,但我们不希望用户被不直观的语法所困扰。 7间隔胜于紧凑 不要在一行中插入太多代码,这会给读者带来...
