(d) Answer the questions (i) to (iv) based on the following : 4

Class Top1(object):

def __init__(self,tx): #Line 1
self.X=tx #Line 2

def ChangeX(self,tx):
self.X=self.X+tx

def ShowX(self):
print self.X

Class Top2(object):
def __init__(self,ty): #Line 3

self.Y=ty #Line 4
def ChangeY(self,ty):
self.Y=self.Y+ty
def ShowY(self):

print self.Y,

class Bottom(Top1,Top2):
def __init__(self,tz): #Line 5
self.Z=tz #Line 6

Top2.__init__(self,2*tz): #Line 7

Top1.__init__(self,3*tz): #Line 8
def ChangeZ(self,tz):
self.Z=self.Z+tz
self.ChangeY(2*tz)

self.ChangeX(3*tz)
def ShowZ(self):
print self.Z,

self.ShowY()
self.ShowX()
B=Bottom(1)

B.ChangeZ(2)
B.ShowZ()
