A - True if len(A) is less than len(B).

B - True if A is a proper subset of B.

C - True if the elements in A when compared are less than the elements in B.

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.
