python property get

Calling getattr(model_class, model_attribute) will return the property object that model_attribute refers to. I'm assuming you already know this and are trying to access the value of the property object. class A(object): def __init__(self): self._myp, get_dict_attr (below) looks up attr in a given object's __dict__ , and returns the associated value if its there. If attr is not a key in that __dict__ , the object's MRO's __dict__ s are searched. If the key is not found, an AttributeError i, The reason is that all attributes are public in Python. Starting names with an underscore or two is just a warning that the given attribute is an implementation detail that may not stay the same in future versions of the code. It doesn't prevent you , You can't put descriptors (like a property object) on the instance. You have to use them on the class. Simply use property as a decorator: class VKHandshakeChecker: @property def answers(self): return self.__answers @property def status(self): return, Is this what you want? class C(object): def __init__(self): self._x = None @property def x(self): """I'm the 'x' property.""" return self._x @x.setter def x(self, value): self._x = value. Taken from http://docs.p,We could make objects out of this class and manipulate the attribute temperature as we wished. Try these on Python shell. >>> # create new object >>> man = Celsius() >>> # set temperature >>> man.temperature = 37 >&g,But Python offers a solution to this problem. The solution is called properties!
