Refer to the above code and write all of the line numbers where an item matching the term is found in the answer box with the same number as the item. Write None if no line contains a matching item. If there is more than one matching line, put the line numbers in ascending order separated by commas. For instance, if the item is Docstring, you should write $4,5,6,7$ in the answer space. Match this format exactly, or you will get the answer wrong, even if you have the right idea. Do NOT use ranges, e$.$g$.47.$
