Understanding Multiple Choice Quiz About Python

• Question 1: Which assertion is correct when talking about the following code:

  def printHello ():
  print ("Hello")
  a = printHello ()

  • printHello () is a function and a is a variable. Both are not objects.
  • Both printHello () and a represent the same object.
  • printHello () and a are two different objects.
  • Syntax error. Cannot assign functions to a variable in Python.
• Question 2: What is the output of the program below?

  def outerFunction ():
  global a
  a = 20
  def innerFunction ():
  global a
  a = 30
  print ('a =', a)
  a = 10
  outerFunction ()
  print ('a =', a)

  • a = 10 a = 30
  • a = 10
  • a = 20
  • a = 30
• Question 3: Which of the following statements is true?
  • Class (class) is a detailed plan for the object.

• Question 4: What is the result of the code below?

  class Foo:
  def printLine (self, line='Python'):
  print (line)

  • There is no right answer.
• Question 6: What is the output of the program below?

  class Point:
  def __init__(self, x = 0, y = 0):
  self.x = x+1
  self.y = y+1

  p1 = Point ()
  print (p1.x, p1.y)

  • 0 0
  • 1 1
  • None
  • xy
• Question 7: Which of the following code uses Python's inheritance feature?

  • class Foo:
    Pass

  • class Foo (object):
    pass

  def __init__(self, x = 0, y = 0):
  self.x = x
  self.y = y

  def __sub__(self, other):
  x = self.x + other.x
  y = self.y + other.y
  return Point (x, y)

  p1 = Point (3, 4)
  p2 = Point (1, 2)
  result = p1-p2
  print (result.x, result.y)

  • 2 2
