Hi Everybody,
It's a little bit, not too much but little out of the scope of this group
but I need the comments of experienced Python developers for that;
Ok, now I'm developing something big, big enough that I need to use heavy
inheritance in my classes. So I have, lets say 2-3 levels of inheritance in
some classes (yeah I know it is not that big for now :) ). My problem is
about the arguments of the classes. Because I'm adding new arguments in
every level of inheritance, I came across a problem of repeating the
arguments in every class that inherits from another class and found a
solution, it is working but I want to be sure about it is Pythonic enough
and correct to use something like this.
Lets say I have a base class called AClass like this:
class AClass(object):
def __init__(self, arg1, arg2):
print arg1, arg2
just for testing purposes I've added print statements to see if it is
working fine.
And another class which derives from AClass and it adds a couple of
arguments to the __init__:
class BClass(AClass):
def __init__(self, arg3=None, arg4=None, *args, **kwargs):
super(BClass,self).__init__(*args, **kwargs)
print arg3, arg4
so my question is, is it good/safe/nice to use *args, **kwargs and pass them
to the super of BClass to avoid repeating the arguments of the parent class
(AClass)?
I've tested the classes with this:
>>> aBObj = BClass(arg1='arg1_test', arg2=10, name='ozgur', email='
[email protected]')
# prints out this
arg1_test 10
ozgur [email protected]
so it is working, but again is it nice to do that?
thank you already for your answers...
