Different methods, same result.

Instead of using a while loop, I called the function again (from within the function) if the input did not equal "DONE". I also printed from within the function rather than after a break. Is either method preferred / better for each of these two differences?

list = []
def taskl():
    task = input("What would you like to add?")
    if task != "DONE":
        list.append(task)
        taskl()
    else:
        print(list)


taskl()

In this case there is no difference, so you should use the one that is more clear or easier. But when you call a function from itself(recursive functions) sometimes it may get tricky so you should definitely be careful and analyze what your code actually does when you're using recursive functions.
