[Tutor] The Card Game

[ALAN GAULD]

I may be wrong but I thought __cmp__ was deprecated. 
In fact I thought it was one oof the things removed in 
Python v3....


But I may have just imagined it! :-)

I would go with __cmp__ which covers them all. 1 for greater, 0 for equal, -1 
for less than.

I am thinking of creating a Card_Value class that will give each rank

You can get cards to compare themselves by adding a few
more "magic methods". Then you can do stuff like

if card1 < card2:
  # ....
elif card2 > card1:
  # ....
else:....

The methods you need to create are
__gt__(), __lt__(), __eq__(), __le__(), __ge__()

for


,<,==,<=,>=

operations.

BTW, In your code you have a comparison using = instead of ==.
That will fail.

HTH,
