For this exercise, how can I edit the existing list variable in the code to add new data items?
A list is an ordered collection of items. Lists are enclosed using the square brackets
 and each item is separated in the list using a comma. To edit an existing list, go the inside of the closing bracket
] and type a comma and then the new item to add to the list. To add multiple items, repeat the process by adding another comma and a new item but do not go beyond the closing square bracket of the list.
my_list = [1, 2, 3, 4] # Edit the list in place. The new list will look like this: my_list = [ 1, 2, 3, 4, 5]
