Odd, I recall this challenge giving an example of the dictionary format. I guess now you just have to guess that it must contain the keywords used in the template.

But anyway, the unpacking operator (also known as "splat") has two forms: * (a single asterisk) for ordinary sequences, and ** (double asterisk) for keyword/value pairs (dictionaries).
