Question

This program will be ran through a Python 3 IDE, please use correct formatting as such.

Write a class named Marsupial that can be used as shown below:

>>> m = Marsupial()
>>> m.put_in_pouch('doll')
>>> m.put_in_pouch('firetruck')
>>> m.put_in_pouch('kitten')
>>> m.pouch_contents()
['doll', 'firetruck', 'kitten']

Now write a class named Kangaroo as a subclass of Marsupial that inherits all the attributes of Marsupial and also:

extends the Marsupial __init__ constructor to take, as input, the coordinates x and y of the Kangaroo object,

supports method jump that takes number values dx and dy as input and moves the kangaroo by dx units along the x-axis and by dy units along the y-axis, and

overloads the __str__ operator so it behaves as shown below.

>>> k = Kangaroo(0,0)
>>> print(k)
I am a Kangaroo located at coordinates (0,0)
>>> k.put_in_pouch('doll')
>>> k.put_in_pouch('firetruck')
>>> k.put_in_pouch('kitten')
>>> k.pouch_contents()
['doll', 'firetruck', 'kitten']
>>> k.jump(1,0)
>>> k.jump(1,0)
>>> k.jump(1,0)
>>> print(k)
I am a Kangaroo located at coordinates (3,0)

Explanation / Answer

# Problem 1
class Marsupial(object):
def __init__(self):
self.lst = []
def put_in_pouch(self, item):
self.lst.append(item)
def pouch_contents(self):
return self.lst

# Problem 2
class Kangaroo(Marsupial):
def __init__(self,x,y):
Marsupial.__init__(self)
self.x = x
self.y = y
def jump(self,dx,dy):
self.x += dx
self.y += dy
def __str__(self):
return 'I am a Kangaroo located at coordinates ({},{})'.format(self.x,self.y)
