获取类中的属性列表

Question

How would I get a list of attributes in a class? For example:

class Test:
    def __init__(self,**kw):
        for k,v in kw.items():
            setattr(self,k,v)
x = Test(value="hello",valueTwo="world")
print(dir(x))

I've done that and it seems to print the keys but, it also prints extra stuff like:

['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__','value','valueTwo']

is there another way to do this so it just gets the keys/values.

Answer 1

Use x.__dict__ :

>>> x.__dict__
{'value': 'hello', 'valueTwo': 'world'}

>>> [ v for k,v in x.__dict__.items() if '__' not in k and 'object at' not in k ]
