How can I make the following code work, and if it's not possible what better ways are there to do this particular thing? I can't seem to figure it out, since I believe I shouldn't create an object of the parent. Just writing super() doesn't seem to work here for me (3.6.5).
class Geometry(object):
def __init__(self, **kwargs):
if kwargs:
allowed = ['lat', 'lng', ]
for k,v in kwargs.items():
if k in allowed:
setattr(self, k, v)
class Address(Geometry):
def __init__(self, d = None):
if d:
for k,v in d.items():
if k in Geometry:
setattr(super, k, v)
if k in Allowed('Address'):
setattr(self, k, v)
I'm trying to push values up to the parent class, but without knowing the attribute names before they are in a list of allowed ones.
I know Geometry doesn't support membership testing as of this moment, because nothing is defined.
The Geometry superclass has the attributes lat, lng, name etc.
The Allowed helper class will return a list of strings representing allowed keys for the Address class.
I'm sure that you are using super in the wrong way.
You should initialise the super class first:
class Geometry(object):
def __init__(self, **kwargs):
if kwargs:
allowed = ['lat', 'lng', ]
for k,v in kwargs.items():
if k in allowed:
setattr(self, k, v)
class Address(Geometry):
def __init__(self, **d = None):
super().__init__(d)
if d:
for k,v in d.items():
if k in Allowed('Address'):
setattr(self, k, v)
In this way, the super class sorts itself out.
Your Address class can sort its own attributes out. (Helped by Allowed).
I've assumed that the d param is a dictionary just like kwargs.
The way you were using super meant to me that you should have just used self. (except that k in Geometry did not really mean anything)
