The generator I designed in the previous section could only deal with lists nested two levels deep, and to do that it used two for loops. What if you have a set of lists nested arbitrarily deeply Perhaps you use them to represent some tree structure, for example. (You can also do that with specific tree classes, but the strategy is the same.) You need a for loop for each level of nesting, but because you don t know how many levels there are, you have to change your solution to be more flexible. It s time to turn to the magic of recursion: def flatten(nested): try: for sublist in nested: for element in flatten(sublist): yield element except TypeError: yield nested

You can now use the book object that was created and tag it with the code shown here: book.tag('A B C D E F') book.save Recall that the save method should return true if the save was successful. You can verify that the book was tagged correctly by executing a search for books that have been tagged with either A or B: Book.find_tagged_with(:any => 'A B')

When flatten is called, you have two possibilities (as is always the case when dealing with recursion): the base case and the recursive case. In the base case, the function is told to flatten a single element (for example, a number), in which case the for loop raises a TypeError (because you re trying to iterate over a number), and the generator simply yields the element. If you are told to flatten a list (or any iterable), however, you have to do some work. You go through all the sublists (some of which may not really be lists) and call flatten on them. Then you yield all the elements of the flattened sublists by using another for loop. It may seem slightly magical, but it works: >>> list(flatten([[[1],2],3,4,[5,[6,7]],8])) [1, 2, 3, 4, 5, 6, 7, 8]
