I think this is a type in the instructions (though I haven’t done the exercise). If you get to use the terminal interface with these exercises that’s the first place to troubleshoot.
However, since that might not be the case, I leave you this clue:
>>> test = {"hello": 1, "world": 2}
>>> test.items()
[('world', 2), ('hello', 1)]
>>> (x,y) = test.items()
>>> x
('world', 2)
>>> y
('hello', 1)
>>> [(x,y)] = test.items()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: too many values to unpack
Notice methodology:
get error
isolate the error data types (dictionaries and the items() method in this case)
