Tuples are sequences just like lists, except they are immutable. Immutable objects cannot be changed or updated in the same way a list can. They are less flexible, however this means they are easier to manage and control. Sorting or extracting parts of a list can bring back unexpected results, and so sometimes the use of tuples can be an advantage.
A tuple is displayed within brackets () and separated by commas. A tuple can contain a mixture of strings and numbers. Here is an example of a tuple:
my_tuple = ('birthday', 'christmas', 'new year', 1988, 2010, 2018)
