isinstance() method is used to find whether the object is instance of class or not.

Q 5 - What is the output of the following code?

def nprint(message, n):
while(n > 0):
   print(message)
n-=1
nprint('z', 5)

Answer : D

Explanation

Because decrementing condition of n' is not present in the while loop.

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 - Which among them is correct(s) about Recursive Function?

A - They are much faster than the normal functions.

B - They take more space then the non-recursive functions.

C - They can always be replaced by non-recursive functions.

D - Using recursive functions however also gives a natural and straight forward simple solution for the program.
