如何在Python中获取实例变量? [英] How to get instance variables in Python?

问题描述

Python中是否有内置方法来获取所有类的实例变量的数组?例如，如果我有以下代码:

Is there a built-in method in Python to get an array of all a class' instance variables? For example, if I have this code:

class hi:
  def __init__(self):
    self.ii = "foo"
    self.kk = "bar"

我有办法做到这一点吗?

Is there a way for me to do this:

>>> mystery_method(hi)
["ii", "kk"]

我本来是错误地要求类变量的.

I originally had asked for class variables erroneously.

推荐答案

每个对象都有一个__dict__变量，其中包含所有变量及其值.

Every object has a __dict__ variable containing all the variables and its values in it.

尝试

>>> hi_obj = hi()
>>> hi_obj.__dict__.keys()
