Python：如何引用一个类本身？(Python: How to refer a class inside itself?)

Python：如何引用一个类本身？(Python: How to refer a class inside itself?) python

试图引用一个类本身。 例如

class Test: FOO_DICT = {1 : Test.bar} # NameError: name 'Test' is not defined @staticmethod def bar(): pass

这种用法有意义吗？ 有更好的选择吗？ 谢谢！

Trying to refer a class inside itself. For e.g.

class Test: FOO_DICT = {1 : Test.bar} # NameError: name 'Test' is not defined @staticmethod def bar(): pass

Does this usage make sense? Any better alternatives? Thanks!

最满意答案

如果您希望字典在类中：首先定义函数并删除Test：

class Test: @staticmethod def bar(): pass FOO_DICT = {1: bar}

If you want the dictionary to be in the class: define the function first and remove Test:

class Test: @staticmethod def bar(): pass FOO_DICT = {1: bar}
