Positional arguments of variable size

Let's practice positional arguments of variable size. Your task is to define the function sort_types(). It takes a variable number of positional arguments and checks if each argument is a number or a string. The checked item is inserted afterwards either in the nums or strings list. Eventually, the function returns a tuple containing these lists.

Use the Python's built-in isinstance() function to check if an object is of a certain type (e.g. isinstance(1, int) returns True) or one of the types (e.g. isinstance(5.65, (int, str)) returns False).

Types to use in this task are int, float, and str.
