Define a function named get_values with two parameters. The first parameter will be a list of dictionaries (the data). The second parameter will be a string (a key). get_values must return a list of strings. For each dictionary in the parameter, you will need the value it associates with the second parameter as a key. If the accumulator list does not contain that value, add it to the accumulator list. After processing the list of dictionaries, the accumulator list's entries will be the values associated with the second parameter, but without any duplicates. You SHOULD assume that all dictionaries in the parameter will have the second parameter as a key.
