如何获取 object 的所有属性及其子对象的属性？

Question

How to use a pythonic way to get all attribute of instance f and get do the same to just obtained attribute.

I want to get ['__init__', 'own', 'Meta', 'field'] , no matter the order.

class Foo:
    def __init__(self) -> None:
        self.own = 'own'

    class Meta:
        field = None


f = Foo()
print(dir(f))

I want to get all attributes of f and the attributes of its subobjects.

if specific_attr in attrs:
    do_something

When i use dir(f) , i got too much value, filtering from this seems a bit troublesome and there is no attribute 'field' , i need to use dir(f.Meta) again.

I want an easy way to get all attributes of instance f and the attributes of its subobjects, my purpose is:

if specific_attr in attrs: do_something

Try

print(dir(Foo))

This should give you the list of properties you want.
