39.) What will be the output of the following code?

class A: A = 1 def __init__(self,v = 2): self.v = v + A.A A.A += 1 def set(self,v): self.v += v A.A += 1 return a = A() a.set(2) print(a.v)

a.) 3 b.) 1 c.) 7 d.) 5

40.) What will be the output of the following code?

a.) it will print True b.) it will print 1 c.) it will raise an exception d.) it will print 0

45.) What will be the result of executing the following code?

class A: def a(self): print('a') class B: def a(self): print('b')
