Write a definition for a class named Kangaroo with the following methods:

  • An __init__ method that initializes an attribute named pouch_contents to an empty list
  • A method named put_in_pouch that takes an object of any type and adds it to pouch_contents.
class Kangaroo:
""" attributes: pouch_contents""" def __init__(self):
self.pouch_contents = list() def __str__(self):
temp = ''
for s in self.pouch_contents:
temp+=str(s)+ '\n'
return temp def put_in_pouch(self,obj):
self.pouch_contents.append(obj) k = Kangaroo()
k.put_in_pouch(1)
k.put_in_pouch(1.0)
k.put_in_pouch('hello sun')
k.put_in_pouch((1,2,3)) k1 = Kangaroo()
k1.put_in_pouch([1,2,3])
k1.put_in_pouch({'':'sun','':'yu'})
k1.put_in_pouch('this is k1')
