Please explain in details.

I think you meant items() (plural). The items method converts a dictionary (kwargs) into a list of key/value tuples.

So then "for key,value in kwargs.items()" is a loop that will operate on each key and value pair.

Finally, "setattr(self,key,value)" will establish an attribute with the same name as key and the value of value.

The entire loop is just a handy way to establish some attributes based on what was in a dictionary.

Does that make it clearer?

I understood the function of items() but can you elaborate the workings of setattr() function ?

Hi Smith Thapa, check out this question in the Treehouse Community: What does setattr() actually do?.

I think the above link/question will help bring clarity to your question, but at a very basic level setattr() just sets values to attributes.
