Get all the decorated properties of a class

I have a class that looks like:

class Test(object):

    @property
    def prop1(self):
        return 5

    @property
    def prop2(self):
        return 10

How do I get back the properties I implemented? For example, [prop1, prop2].

I have tried vars() and dir() but these seem to also return hidden/special methods.

Is the only way to do this to parse through the results that don't have underscores for say dir()?

You can use following:

def isprop(v):
    return isinstance(v, property)
propnames = [name for (name, value) in inspect.getmembers(Test, isprop)]

Try this

>>>[ k for k,v in Test.__dict__.items() if isinstance(v, property) ]
['prop1', 'prop2']

Since property is a type we can use isinstance to find it in the class' internal dictionary.
