# Python3 code here for creating class
class geeks:
	def __init__(self, x, y):
		self.x = x
		self.y = y
		
	def Sum(self):
		print( self.x + self.y )

# creating list	
list = []

# appending instances to list
list.append( geeks(2, 3) )
list.append( geeks(12, 13) )
list.append( geeks(22, 33) )

for obj in list:
	# calling method
	obj.Sum()

# We can also access instances method
# as list[0].Sum() , list[1].Sum() and so on.
