3.6.11 Lists
Lists are used to store multiple items in a single variable, and are created using square brackets:
B_list = ["Blossom", "Bubbles","Buttercup"]
print(B_list)
List items are changeable, ordered, and allow duplicate values. The list items are indexed, with the first item having
index [0], the second item having index [1], and so on.
C_list = ["Red", "Blue", "Green", "Blue"]
print(C_list) # duplicate
print(C_list[0])
print(C_list[1]) # ordered
C_list[2] = "Purple" # changeable
print(C_list)
>>> %Run -c $EDITOR_CONTENT
