Extend a list
If you can change elements in a list, you sure want to be able to add elements to it, right? You can use the + operator:
x = ["a", "b", "c", "d"]
y = x + ["e", "f"]
You just won the lottery, awesome! You decide to build a poolhouse and a garage. Can you add the information to the areas list?

areas = ["hallway", 11.25, "kitchen", 18.0, "chill zone", 20.0,
"bedroom", 10.75, "bathroom", 10.50]
# Add poolhouse data to areas, new list is areas_1
areas_1 = ____
# Add garage data to areas_1, new list is areas_2
areas_2 = ____This exercise is part of the course
