from my understanding, a list can do everything a tuple can do plus more. The big advantage of using a list is you can change elements, lists are mutable. Are their situations where a tuple is preferable to a list?
Tuples are handy for transferring multiple data, for instance to and from a function. They are easy to construct and transfer and assign their data easily. Check the multiReturn() example in the "Starting Python" sticky to see what I mean.
