python - 类型错误:必须使用 Interface 实例作为第一个参数来调用未绑定(bind)方法 getInterfaceName()(什么也没有)

您没有向我们展示导致错误的 getInterfaceName() 调用，这使得我们更难为您提供帮助。

但是，我猜调用看起来像这样:

something = Interface.getInterfaceName()

你不能那样做。您必须创建 Interface 的实例，然后调用其 .getInterfaceName() 方法:

myInterface = Interface()
something = myInterface.getInterfaceName()
