What's the difference between using () and [] for lists?

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

What 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

Brackets [] will create lists, parentheses () create tuples. They can be used in similar ways, but one of the differences is that tuples are immutable.

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

Like Steven said, brackets will create what is known in other programming language as arrays and parenthesis will create what is known as tuples. If you want to learn more about the difference between tuples and lists, here is a I have a link for you: https://www.afternerd.com/blog/difference-between-list-tuple/

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