-Note that when an argument is already inside an `iterable` such as a `tuple` or `list`, it needs to be [_unpacked_][unpacking-and-multiple-assignment] before being passed to a function that takes an arbitrary number of separate arguments.
+Note that when an argument is already inside an `iterable` (_such as a `tuple` or `list`_), it needs to be [_unpacked_][unpacking-and-multiple-assignment] before being passed to a function that takes an arbitrary number of separate arguments.
 This is accomplished by using `*`, which is the [unpacking operator][unpacking operator].
 
 `*` in this context _unpacks_ the container into its separate elements which are then transformed by `*args` into a `tuple`.
