Ch. 9 Exam Review

What is wrong with the following attempt to initialize a list? data = ["hockey", 4, False]

• You should be using parentheses ( ) to surround the items in a list

• "data" is not a valid variable name

• You can't mix different types of data in a single list

• Nothing; this will work correctly

What will be displayed on the screen when the following code is run? esports = ["Donkey Kong", "Galaga", "Pac Man"] print( esports[1] )

• Donkey Kong

• Galaga

• Pac Man

• Syntax error; you can't access individual list items this way

What is wrong with the following code? esports = ("Donkey Kong", "Galaga", "Pac Man") esports[1] = "Centipede"

• You cannot update an item in a tuple

• The item at index 1 does not exist

• The [1] notation after the variable name is not valid

• Nothing; this will work fine

Given a list with 3 items, what is the lowest and highest valid index number into that list?

• 0 and 2

• 1 and 3

• 0 and 3

• 1 and 2

Given a list named "esports", which of the following statements will access only the first and second items in that list?

• esports(0:1)

• esports{0:2]

• esports(1,2)

• esports.range(0,2)

What is displayed on the output screen when the following code runs? esports = ("Donkey Kong", "Galaga", "Pac Man") print(len(esports))

• 3

• ('Donkey Kong', 'Galaga', 'Pac Man')

• esports

• Error; the len() function will not work on a tuple

What is displayed to the screen when the following code runs? esports = ["Donkey Kong", "Galaga", "Pac Man"] esports.insert(0,"Centipede") print(esports)

• ['Centipede', 'Galaga', 'Pac Man']

• ['Donkey Kong', 'Galaga', 'Pac Man', 'Centipede']

• ['Centipede', 'Donkey Kong', 'Galaga', 'Pac Man']

• ['Centipede', 'Centipede', 'Centipede']

What is displayed to the screen when the following code runs? esports = ["Donkey Kong", "Galaga", "Pac Man"] esports.reverse() print(esports)

• ['Pac Man', 'Galaga', 'Donkey Kong']

• ['Donkey Kong', 'Galaga', 'Pac Man']

• ['gnoK yeknoD', 'alagaG', 'naM caP']

• Error; you cannot use the reverse() function on a list

What is displayed on the screen when the following code runs? esports = ["Donkey Kong", "Galaga", "Pac Man"] item = esports.pop(0) print(esports)

• ['Galaga', 'Pac Man']

• ['Donkey Kong', 'Galaga', 'Pac Man']

• ['Donkey Kong']

• ['Donkey Kong', 'Galaga']

What is displayed on the screen when the following code runs? esports = ["Donkey Kong", "Galaga", "Pac Man"] if ("Galaga" in esports): print("Found it") else: print("Not here")

• Found it

• Not here

• Both "Found it" and "Not here"

• Nothing - there is no output at all
