Slicing and dicing

Selecting single values from a list is just one part of the story. It's also possible to slice your list, which means selecting multiple elements from your list. Use the following syntax:

my_list[start:end]

The start index will be included, while the end index is not.

The code sample below shows an example. A list with "b" and "c", corresponding to indexes 1 and 2, are selected from a list x:

x = ["a", "b", "c", "d"]
x[1:3]

The elements with index 1 and 2 are included, while the element with index 3 is not.

Use slicing to create a list, downstairs, that contains the first 6 elements of areas.
Do a similar thing to create a new variable, upstairs, that contains the last 4 elements of areas.
Print both downstairs and upstairs using print().
