MyClass.class_method("example argument") 在上面的示例中,class_method被@classmethod修饰器修饰,因此它成为了一个类方法。该方法的第一个参数是cls,代表调用该方法的类本身。在class_method中,可以通过cls参数访问类变量class_var。最后一行代码调用了MyClass.class_method方法,并传递了一个字符串参数,该方法打印了...
implementAbstractClasses: enables code action to implement methods of classes inherited from an abstract class, using AI suggestions from GitHub Copilot to populate the method body. Usage example:{"implementAbstractClasses": true} autoFormatStringsfalseWhen typing "{" inside a string, whether to auto...
