until(self, method, message='')：这接受一个方法作为参数和一个可选消息。until 在固定的时间跨度（即 poll_frequency [500ms 默认值]）之后重复调用此方法。只有当返回值不为“False”时，指定方法的调用才会停止，即，直到该方法返回 Success。until_not(self, method, message=''): until_not 很像直到。...

The decorator approach for creating properties requires defining a first method using the public name for the underlying managed attribute, which is .radius in this example. This method should implement the getter logic. In the above example, lines 5 to 9 implement that method....
method() #测试方法 绑定方法已经绑定了对象示例,调用的时刻不用也不能传入self参数了。 注:使用对象访问实例方法为何会返回绑定方法?这个还得等到学完“魔法方法”才能解释,内部其实是拦截对方法成员的访问,返回了一个Callable对象。 私有成员 代码语言:javascript 代码运行次数:0 运行 AI代码解释 1 # 私有成员 2 ...
When a method or attribute of a class is accessed, Python uses the class MRO to find it. The MRO is also used by super() to determine which method or attribute to invoke. You can learn more about super() in Supercharge Your Classes With Python super(). You can evaluate the Temporary...

注册方式的缺点:不会出现在类的MRO(Method Resolution Order),故而也不能通过super()来调用抽象方法。当没有实现抽象方法时,实例化时候不会报错,只有在调用时候才会报错。 继承方法 直接从抽象基类派生子类有一个好处,除非子类实现抽象基类的抽象方法,否则子类不能实例化。
