Program Skeleton 2

Adding in the __str__ methods gives us:

which when run produces,

>>> 
d after shuffling = 
d has None cards
Your hand of None cards contains: 
Your hand of None cards contains: 
There are None cards left in the deck.
>>> 

Note that we can't use pass in the __str__ methods because they are required to return a string, so instead we return a null string in each one.
