I would like to know how to convert a python object from a dictionary (using python3 btw). I realize that this question has been asked (and answered) already ([here](https://stackoverflow.com/questions/61517/python-dictionary-from-an-objects-fields)). However, in my case the object is given entirely in terms of `@property` values, for example:

```
class Test: 
    @property  
    def value(self): 
        return 1.0       

```

Regarding conversion to a dictionary: The `__dict__` dictionary of the `Test` class is empty, and consequently, the `vars` 
function does not work as expected:

```
>>> vars(Test()) 
{}

```

Still, I can use `gettattr(Test(), 'value')`, to obtain `1.0`, so
the value is present.

Note: The reason I am coming up with this apparently contrived example is that I am trying to convert a cython `cdef class` (containing parameters) to a dictionary. The recommended way to wrap c structures with properties using cython is indeed based on [properties](https://cython.readthedocs.io/en/latest/src/userguide/extension_types.html#properties).
