• coffee = "kona"

  tea = "mango"

  smoothie = "raspberry"

• coffee = "raspberry"

  tea = "mango"

  smoothie = "kona"

• coffee = "kona"

  tea = "kona"

  smoothie = "kona"

• coffee = ["kona", "mango", "raspberry"]

  tea = ["kona", "mango", "raspberry"]

  smoothie = ["kona", "mango", "raspberry"]

• I only

• II only

• Both I and II

• Neither I nor II

What does “packing” refer to in Python?

• Creating a list

• Initializing variables using values from a list

• Storing multiple variables’ values by putting them in a collection, like a list or tuple

• Cramming as many commands as possible onto a single line

• red = "RED"

  blue = "BLUE"

  green = "GREEN"

• red = "BLUE"

  blue = "GREEN"

  green = "RED"

• red = ["BLUE", "GREEN", "RED"]

  blue = ["BLUE", "GREEN", "RED"]

  green = ["BLUE", "GREEN", "RED"]

• red = "BLUE"

  blue = "BLUE"

  green = "BLUE"

• board = [1, 2, 3] + [4, 5, 6] + [7, 8, 9]

• board = [1, 2, 3]

  board.append([4, 5, 6])

  board.append([7, 8, 9])

• board = [1, 2, 3, 4, 5, 6, 7, 8, 9]

• board = []

  board.append([1, 2, 3])

  board.append([4, 5, 6])

  board.append([7, 8, 9])

• print(my_list[1])

• print(my_list[1:2])

• print(my_list[1][2])

• print(my_list[2][3])

What does “unpacking” refer to in Python?

• Creating a list

• Initializing multiple variables at a time using a collection of values

• Storing multiple variables’ values by putting them in a collection, like a list or tuple

• Cramming as many commands as possible onto a single line

• my_list = [i for i in range(6)]

• my_list = [i*2 for i in range(6)]

• my_list = [i for i*2 in range(6)]

• This cannot be done using a list comprehension statement.
