如何从 Python 中的静态方法获取(子)类名? [英] How to get (sub)class name from a static method in Python?

问题描述

如果我定义:

class Bar(object):

    @staticmethod
    def bar():
        # code
        pass

class Foo(Bar):
    # code
    pass

是否可以通过函数调用 Foo.bar() 来确定类名 Foo?

Is it possible for a function call Foo.bar() to determine the class name Foo?

推荐答案

用类方法替换静态方法.这将在调用时传递类，因此您可以从中获取类名.

Replace the staticmethod with a classmethod. This will be passed the class when it is called, so you can get the class name from that.

class Bar(object):

    @classmethod
    def bar(cls):
        # code
        print cls.__name__

class Foo(Bar):
    # code
    pass

>>> Bar.bar()
Bar

>>> Foo.bar()
Foo
