Hey guys, can one of you just point briefly out, when it is recommended to use **kwargs at an instance and when not?
At the exercises I always trying to do the next steps on my own before I watch the video and there I noticed that I struggle with it, when to use **kwargs and not.
Thanks for your help, Cheers Urs

If you can use named variables and named variables-with-default values explicitly, then you don't (and probably shouldn't) use the wildcard parameters **kwargs or **args.
If used **kwargs must be the last parameter.
Comment if you have more questions.
