As an example of a library built on template strings for i18n, see the Python Forums on Bytes. This ability of sending in all items in a particular iterable as separate arguments wouldn’t be possible without *, unless the list was a fixed length. Here we only have a single element to be used in our string formatting, and thus we're not required to enclose the element in a tuple like the previous examples.
