Step 1: Update classes in objects.py: You will update the classes in the objects.py in the following way: 1. Card Class: a. You will make the Card class comparable so that when a hand is displayed, the cards in the hand are shown in a sorted order (what set of special methods will you need to add?). Remember that when comparing two cards, you want to compare their suit attributes first and then the rank attributes. Note that the suits follow this order: Spades > Hearts > Diamonds > Clubs. (Luckily, these are alphabetically ordered as well!) The ranks follow this order: Ace > King > Queen > Jack > 10 >9 >8>7>6>5>4>3 > 2. There are many ways to implement this.1 b. You will make the card class printable. You should replace the display Card method with one of the special methods. (Which one?) 2. Deck and Hand Classes: a. Make the Deck and Hand classes iterable, by adding a Generator function as we discussed in the class. 1 One possible way is to have a dictionary, say RANKORDER defined whose keys are the possible ranks ("Ace", King, ... "4","3","2"), and values are some integers that match the desired ordering of the ranks. E.g. RANKORDER = { "2":2,"3":3, .... "10": 10,"Jack":11,"Queen":12, King: 13,"Ace":14} Clearly RANKORDER["2"] 21 points), if so return iii. otherwise, repeat from step a. d.
