I've seen a couple of people using parenthesis instead of [] for lists, is there any difference between them? Thanks

There's a another course similar to this one called Introducing Tuples that you might enjoy.

230,688 PointsBoth types of symbols have different meanings when placed after an identifier. The meanings discussed above only apply when they are used by themselves.

1,387 PointsWhat is confusing is that the banner = list ("Congratulations") you have this little jump in knowledge I think, where you create a list from the word Congratulations that has been introduced in an unexplained way.I understand Tuples are different from list but there is no explanation on the use of "list("Congratulations")" example and this is confusing
