Q 5 - Find the output of the code?

def f(a, b = 1, c = 2):
   print('a is: ',a, 'b is: ', b, 'c is: ', c)
f(2, c = 2)
f(c = 100, a = 110)

A - a is: 2 b is: 1 c is: 2

a is: 110 b is: 1 c is: 100

B - a is: 2 b is: 2 c is: 2

a is: 110 b is: 2 c is: 100

C - a is: 0 b is: 2 c is: 2

a is: 110 b is: 0 c is: 100

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.
