Python检查类的实例 [英] Python check instances of classes

问题描述

有什么方法可以检查对象是否是类的实例?不是具体类的实例，而是任何类的实例.

Is there any way to check if object is an instance of a class? Not an instance of a concrete class, but an instance of any class.

我可以检查对象不是类，不是模块，不是回溯等，但是我对简单的解决方案感兴趣.

I can check that an object is not a class, not a module, not a traceback etc., but I am interested in a simple solution.

推荐答案

isinstance()是您的朋友.它返回一个布尔值，并且可以通过以下方式用于检查类型.

isinstance() is your friend here. It returns a boolean and can be used in the following ways to check types.

if isinstance(obj, (int, long, float, complex)):
    print obj, "is a built-in number type"

if isinstance(obj, MyClass):
    print obj, "is of type MyClass"

希望这会有所帮助.
