Python: AttributeError: can't set attribute. I can't create my instance

  • 772

I have an error when creating my instance

#! python3

class Profile(object):
    """contiene la informacion del perfil"""
    def __init__(self):
        self.name = None    

    @property
    def name(self):
        """name"""
        return self.name

if __name__ == '__main__':
    profile1 = Profile()

The error that throws me:

Traceback (most recent call last):
File "F:\Project\profile.py", line 14, in <module>
  profile1 = Profile()
File "F:\Project\profile.py", line 6, in __init__
  self.name = None  
AttributeError: can't set attribute

I've been turning it around for a while, but I don't see any sense in it

    The problem is caused because your attribute self.nameis colliding with the property name, and by doing so it wants to use the property's setter. The common thing is to set the name of the attribute with: _, for example in your case it changes self.namewith self._name.

    class Profile(object):
    """contiene la informacion del perfil"""
    def __init__(self):
        self._name = None    

    @property
    def name(self):
        return self._name

if __name__ == '__main__':
    profile1 = Profile()

    Or implement the setter:

    class Profile(object):
    """contiene la informacion del perfil"""
    def __init__(self):
        self.name = None    

    @property
    def name(self):
        return self._name

    @name.setter
    def name(self, value):
        self._name = value

if __name__ == '__main__':
    profile1 = Profile()
