hello everyone.
if i make a class like this

class A:
    def __init__(self,name):
        self.name=name

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=address

but instances of B have addresses also.
how can B inherit its name from initializing A?

if my question makes any sense , please explain?

[my reply:]

Your question makes perfect sense. You just need to pass name as an argument
to B( ) so it can forward it on to A's __init__:

class A:
    def __init__(self,name):
        self.name=name

class B(A):
    def __init__(self, name, address):    ## added name parameter
        A.__init__(self,name)
        self.address=address

me = B('Don','12345 Main St')

print me.name
print me.address

>>> Don
>>> 12345 Main St

HTH,
Don
