Can someone please help me with the error above in line 48.
Thank you.
In your functon declaration, the
*args catches all positional parameters, so "setting" must be an option keyword parameter.I don't see much benefint in being able to set several settings to the same value so you can just as well use simpler
setting_name, setting_value args.

Can you please write in the code and give it to me

No, because I don't want to influence you one way or another. Either you are a seasoned python programmer and you know what you are doing when you use constructs such as
*args, or the consequences are a bit above your head right now and you write code that you completely understand. No shame doing so. And IMHO there is no need for such constructs here (in both the get..() and the set...()).PS: is your getConfigSettting() method really working when you give several arguments?

yeaaah brah it's working
RE: setconfig setting - nilamo - May-22-2017
You could just delete the method, since you never call it anyway.
