Keyword arguments of variable size
Now let's move to keyword arguments of variable size! Your task is to define the function key_types(). It should take a variable number of keyword arguments and return a new dictionary: the keys are unique object types of arguments passed to the key_types() function and the associated values represent lists. Each list should contain argument names that follow the type defined as a key (e.g. calling the key_types(kwarg1='a', kwarg2='b', kwarg3=1) results in {<class 'int'>: ['kwarg3'], <class 'str'>: ['kwarg1', 'kwarg2']}).
To retrieve the type of an object, you need to use the type() function (e.g. type(1) is int).
