card - A basic playing card

A simple API for creating and using playing cards

We will be using numbers to represent playing card clubs and ranks. These are the suits:

suits

['♣️', '♦️', '♥️', '♠️']

For instance the suit at index 0:

suits[0]

'♣️'

These are the ranks

ranks

[None, 'A', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K']

For instance the rank at index ‘1’ (not that there isn’t a playing card at position ‘0’, since we want the ranks to match the indices where possible)

ranks[1]

'A'

 Card (suit:int, rank:int)

A playing card, created by passing in ‘rank’ from ‘ranks’ and ‘suit’ from ‘suits’

	Type	Details
suit	int	An index into ’suits
rank	int	An index into ‘ranks’

Here is an example:

c = Card(suit=1, rank=3)
c

3♦️

Comparison operators

Equality, less than, and greater than work on the rank and suit indices:

For instance here are a test for quality…

test_eq(Card(suit=1, rank=3),Card(suit=1, rank=3))

… and a test of ‘<’

assert Card(suit=1, rank=3)<Card(suit=2, rank=3)

…and finally of >:

assert  Card(suit=3, rank=3)>Card(suit=2, rank=3)
assert not Card(suit=1, rank=3)>Card(suit=2, rank=3)
