| 6 | +We will be using numbers to represent playing card clubs and ranks. |
| 7 | +These are the suits: |
| 8 | + |
| 9 | +``` python |
| 10 | +suits |
| 11 | +``` |
| 12 | + |
| 13 | + ['♣️', '♦️', '❤️', '♠️'] |
| 14 | + |
| 15 | +For instance the suit at index `0`: |
| 16 | + |
| 17 | +``` python |
| 18 | +suits[0] |
| 19 | +``` |
| 20 | + |
| 21 | + '♣️' |
| 22 | + |
| 23 | +These are the ranks: |
| 24 | + |
| 25 | +``` python |
| 26 | +ranks |
| 27 | +``` |
| 28 | + |
| 29 | + [None, 'A', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K'] |
| 30 | + |
| 31 | +For instance the rank at index `1` (note that there isn’t a playing card |
| 32 | +at position `0`, since we want the ranks to match the indicies where |
| 33 | +possible): |
| 34 | + |
| 35 | +``` python |
| 36 | +ranks[1] |
| 37 | +``` |
| 38 | + |
| 39 | + 'A' |

| 48 | + |
| 49 | +``` python |
| 50 | + |
| 51 | +def Card( |
| 52 | + suit:int, # An index into `suits` |
| 53 | + rank:int, # An index into `ranks` |
| 54 | +): |
| 55 | + |
| 56 | +``` |
| 57 | + |
| 58 | +*A playing card* |
| 59 | + |
| 60 | +Here’s an example of creating and displaying a card: |
| 61 | + |
| 62 | +``` python |
| 63 | +c = Card(suit=1, rank=3) |
| 64 | +c |
| 65 | +``` |

| 70 | + |
| 71 | +Equality, less than, and greater than work on the rank and suit indices. |
