从静态方法访问静态变量

本文介绍了从静态方法访问静态变量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想从静态方法访问静态变量:

I want to access a static variable from a static method:

#!/usr/bin/env python class Messenger: name = "world" @staticmethod def get_msg(grrrr): return "hello " + grrrr.name print Messenger.get_msg(Messenger)

如何在不将grrrr传递给方法的情况下执行此操作?这是真正的面向对象吗?..

How to do it without passing grrrr to a method? Is this the true OOP?..

name或self.name之类的东西似乎都不起作用:

Anything like name or self.name seems not working:

NameError: global name 'name' is not defined

和

NameError: global name 'self' is not defined

推荐答案

使用@classmethod代替@staticmethod.在写完问题后才发现它.

Use @classmethod instead of @staticmethod. Found it just after writing the question.

在许多语言(C ++，Java等)中，静态"和类"方法是同义词. 不在Python中.

In many languages (C++, Java etc.) "static" and "class" methods are synonyms. Not in Python.
