When you define a function, you are writing a block of code which you can ask to perform a task. The task may be simple, and not require any additional information, or it may be more complex and need information. Take a simple analogy. Let's suppose I gave you the instruction "Switch off the light" and there was only one light, you wouldn't need any more information. We could call that: def toggleLight(): Now let's take a more complicated examle - making tea. If I give you the instruction "Make me a cup of tea" you might ask questions like "Milk? Sugar? Kind of tea?" I need to give you this information before you can perform the task. Similarly in a function - you may need to pass information (arguments) to the function. Here's the tea example: def makeTea(sugar, milk, kind): We might call the function as follows: makeTea(2, "none", "darjeeling") The internals of the function would be able to parse the arguments you gave it, and carry out the task you've asked it to do. As to when to use which, I think you'll find that most of the functions you write will require information if they're to be of much use. Only a very simple function doesn't take any arguments.
