A - B.isinstance(O)

B - O.isinstance(B)

C - isinstance(O,B)

D - isinstance(B,O)

Q 5 - What is the output of the code?

def f():
   global z
   print('z is: ', z)
   z=50
   print('new value of global z is: ', z)

f()
   print('Value of z is: ', z)

A - z is 100

new value of global z is: 100

value of z is 100

B - z is 100

new value of global z is: 100

value of z is 50

C - z is 100

new value of global z is: 50

value of z is 100

D - z is 100

new value of global z is: 50

value of z is 50

Answer : D

Explanation

Here in the above code ‘global’ keyword is used to state that ‘z’ is global variable. So when we assign a value to z in the function then the new assigned value is reflected whenever we use the value of ‘z’ in the main block or outside the function.

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()

A - 300 400

B - 100 400

C - 100 200

D - 300 200

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.

Answer : C

Explanation

+ Operator cannot be operated on the sets.
