理解Python中的Class、Instance和Method的关键在于区分"类"和"对象"的概念。当我们在编程中提到Class时，可以将其比喻为生产路由器的工厂，而Instance则是工厂生产出的具体路由器。在类的定义过程中，如创建了一个名为Router的类，这相当于建厂，而通过这个类生产出一台Huawei路由器，则是类的实例化。在...

classAbelApp(abel):def … Python 中的变量名解析遵循LEGB原则,本地作用域(Local),上一层结构中的def或Lambda的本地作用域(Enclosing),全局作用域(Global),内置作用域(Builtin),按顺序查找。 和变量解析不同,Python 会按照特定的顺序遍历继承树,就是方法解析顺序(Method Resolution Order,MRO)。类都有一个名...

To pass arguments to a custom thread type, redefine the constructor to save the values in an instance attribute that can be seen in the subclass. 因为args和kwargs参数在Thread构造的时候被保存为私有成员变量,子类不容易访问他们。为了传递参数,在样例程序中重定义构造函数让它们在子类中变成可见的!
