You've now seen the most important methods that you'll be using on lists and strings,
and a few more obscure ones that you'll only rarely use.
You should now be able to read and write code using those methods,
you should be able to extend the list using
either append or concatenate to add more items onto the end of it,
and you should be able to identify whether a method mutates
an object or creates a modified copy of it,
methods on tuples and strings,
reminder they can never mutate them they,
can only make modified copies because tuples and strings are immutable.
Some operations on lists mutate them; assignment,
deletion, append, insert, reverse,
sort, remove, and pop.
Those are mutate lists index and count,
leave them alone and just tell you some property of those lists.
So, today's joke, how can you get two cats in the same room?
You can catenate them,
see you on the flip side.
