Python Lists

How do you create an empty list in python

• [ ]

• { }

• ( )

How to create a new empty list in python

• [ ]

• list ( )

• list.init( )

• create.list ( )

grades = [2.0, 3.0, 4.0]

Which of the following code can be used to iterate over the grades list ?

• for grade in grades :

  # todo

• i = 0

  while i < len(grades) :

  #todo

  i = i + 1

• [print ( i ) for i in grades]

• for i, grade in enumerate(grades) :

  # todo

grades = [2.0, 3.0, 4.0]

How do you get the length of the list above

• len(grades)

• length(grades)

• list.length(grades)

• list.len(grades)

a = [ 1, 3, 5 ]

b = [ 7, 9, 11 ]

How do you merge these two lists ?

• a + b

• a.extend(b)

• a.merge(b)

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

numbers [-3]

What is numbers [-3]

• 8

• 9

• 7

numbers = [1,2,3,4,5,6,7,8,9,10]

print ( numbers[-3] == numbers[7])

The output of the program above is

• True

• False

numbers = [1,3,5,7]

Which of the following code inserts 9 into the list above at index 2

• numbers.insert(2,9)

• numbers.insert(1,9)

• numbers.insert(3,9)

numbers = [1, 2, 3, 4, 5]

Which of the following code changes the element 4 to 9

• numbers[3] = 9

• numbers[4] = 9

numbers = [1, 2, 3, 4, 5]

print ( numbers.pop() )

The program above prints

• 5

• syntax error

• 1

• [2, 3, 4, 5]
