Explanation

The use of a single asterisk (*) before the parameter name (arg) indicates that it can accept a variable number of unnamed positional arguments. When the function is called, these arguments will be collected into a tuple named arg. The args parameter, with two asterisks (), allows for a variable number of keyword arguments to be passed to the function. These arguments will be collected into a dictionary named args.
