The question:

    Dictionaries use what special operator to unpack: 
        for example, when using str.format(________my_dictionary ). 
    Tuples, however, use the alternative string.format(________my_tuple).

refers to using the "**" and "*" to unpack containers. "**" is used to unpack dictionaries into keyword arguments and "*" is used to unpack tuples into positional arguments:

    Dictionaries use what special operator to unpack: 
        for example, when using str.format(**my_dictionary ). 
    Tuples, however, use the alternative string.format(*my_tuple).
