A - 3 4 5 6 7 8 9 10 11 12

B - 3 4 5 6 7 8 9

C - 3 4 5 6 7 8 9 10 11

Q 4 - what is output of following code −

class Count:
   def __init__(self, count=0):
      self.__count=count
a=Count(2)
b=Count(2)
print(id(a)==id(b), end = '' '')

c= ''hello''
d= ''hello''
print(id(c)==id(d))

Answer : B

Explanation

The objects with same contents share the same object in the python library but this is not true for custom-defined immutable classes.

Q 5 - What is output of following code −

l = [1,2,6,5,7,8]
l.insert(9)

A - l=[9,1,2,6,5,7,8]

B - l=[1,2,6,5,9.7,8] (insert randomly at any position)

C - l=[1,2,6,5,7,8,9]

D - Type Error

Answer : D

Explanation

listname.insert(x,y) method is used to insert a item at certain position in a list. x defines position at which the element will be added and y defines the element to be added in the list. And insert function takes exactly two arguments else it results in type error.

Q 6 - What is the output of the following code?

class P: 
   def __init__(self): 
      self.__x=100 
      self.y=200 
   def print(self): 
      print(self.__x, self.y)  
class C(P): 
   def __init__(self): 
      super().__init__() 
      self.__x=300 
      self.y=400  
d = C() 
d.print()

Answer : B

Explanation

In the above code x is a private variable declared in the class P. Thus value of x cannot be changed in the class C which inherits class P. But y is not a private variable thus its value can be changed.

Q 7 - Suppose we are given with two sets(s1&s2) then what is the output of the code −
