Made some changes to accessing pieces of arrays while doing a test recording.
Creating a tuple:\\
{\ex \lstinline| t = (1, "hello", 2.5)|}
Accessing elements of tuples:\\
{\ex \lstinline| t[index] Ex: t[2]|}
Accessing slices of tuples:\\
{\ex \lstinline| t[start:stop:step]|}
Swapping values:\\
{\ex \lstinline| a, b = b, a|}
