☞Tuples can be converted into lists, and vice-versa. The built-in tuple() function takes a list and returns a tuple with the same elements, and the list() function takes a tuple and returns a list. In effect, tuple() freezes a list, and list() thaws a tuple. -

This has all kinds of uses. I often want to assign names to a range of values.
