As in add another argument to B's initializer? e.g.
class B(A):
def __init__(self, name, address):
A.__init__(self, name)
self.address =3D address
Now, with
b =3D B('John Doe', 'Homeless')
you just get his name via b.name.
If you have any questions keep hollering
With my best regards,
G. Rodrigues

Subject: [Tutor] inheriting __init__ arguments
hello everyone.=20
if i make a class like this
class A:
def __init__(self,name):
self.name=3Dname
then i make another class that inherits from A its name attribute
class B(A):
def __init__(self, address):
A.__init__(self,name)
self.address=3Daddress
but instances of B have addresses also.
how can B inherit its name from initializing A?
if my question makes any sense , please explain?
