As given, never. Nor would you need: num = 0 print(num) It's pretty boring, trivial code that does nothing interesting. And you could simplify it, make it even more trivial: print([]) Why would you do that? You probably wouldn't bother. But each line is very useful, if taken as part of a bigger, more useful program! Look at the first line: word = [] This creates a variable, "word", and assigns an empty list to it. But once you have an empty list, you can start putting things into it. Once you have a list with items in it, there are all sorts of things you can usefully do: - append items to the end; - insert items at the start or the middle; - sort the list; - reverse the list; - pull items out of the list; - count how many items are in the list; - search for matching items and many more. The sky is the limit, and that's what programming is about. Just because the list *starts* as empty doesn't mean it must remain empty forever. -- Steven “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
