This object is simply a Python list of Python sets, with the "outer list containing playlists and each playlist consisting only of distinct artist strings (without postprocessing per Exercise 2-we'll handle that later). Exercise 3: extract_playlists (2 points) Complete the function, extract_playlists(users), so that it returns the simplified list of artist names as shown above. For instance, calling extract playlists(exe_deno users) should return an object that matches ex3_demo_output. Note : You should not process the artist names per Exercise 2, that step comes later Note 1: You should preserve the exact order of playlists from the input. That is, you should loop over users and playlists in the order that they appear in the input and produce the corresponding output in that same order. Note 2 Do not forget that the final output should be a Python list (holding playlists) of Python sets (unprocessed artist names) Note 3 Your function should not modify the input dataset, In (396): def extract_playlists(users): ### YOUR CODE GOES HERE File " Line 4 SyntaxError: unexpected EOF while parsing In (316): # Demo cell ex3_your_output extract.playlists (exe_demo users print("-w.
