It fills the empty values with None, and returns an iterator of tuples. The izip() function also expects a container such as a list or string as input. Then you can simplify the code in the body of the loop by flattening the sequence of paired items and filtering out the None values, and in your case, 0 values. Also you use insert a lot. The resulting list is truncated to the length of the shortest input iterable. This means that the resulting list of tuples will take the form [(numbers[0], letters[0]), (numbers[1], letters[1]),, (numbers[n], letters[n])]. One solution could be using a third list that contains all the elements of the two original lists. In this case, the zip_longest() function replaces and maps the equivalent element with a None value.
