+ "Python builtin container types like lists, tuples, dicts, and sets are very flexible. However, these types don't store things efficiently when it comes to many elements. Everything in python (even integers) are complete python objects. They take up much more memory and are harder to use efficiently than their C-level counterparts. Not only that, but it isn't easy to perform basic arithmetic on the numbers in these containers."
