 `args` is the name given to the `tuple` of arguments,  but it could be any other valid Python name, such as `my_args`, `arguments`, etc.
 The `*` is the operator which transforms the group of separate arguments into a [`tuple`][tuple].

 If you have ever [unpacked a tuple][unpack a tuple] you may find the `*` in `*args` to be confusing.
 The `*` in a _parameter_ definition, instead of unpacking a tuple, converts one or more positional arguments _into_ a tuple.
 
 We say that the `*` operator is [overloaded], as it has different behavior in different contexts.
 For instance, `*` is used for multiplication, it is used for unpacking, and it is used to define an arbitrary number of positional parameters.

 Since a tuple can be iterated, `args` can be passed to any other function which takes an iterable.
 Although `*args` is commonly juxtaposed with `**kwargs`, it doesn't have to be.
