A playing card consists of a suit ("Hearts", "Spades", "Clubs", "Diamonds") and a rank (2, 3, 4, 5, 6, 7, 8, 9, 10, "Jack", "Queen", "King", "Ace"). Implement a Card class. Implement that cards are equal when they have an equal rank, and that the other comparisons use the ranks in the order given above (2 lowest, Ace highest). Test the class.

Assignment

Define a class Card that can be used to represent playing cards. Two arguments must be passed when creating a new card (Card): i) the suit (str) of the card, which must be one of 'Hearts', 'Spades', 'Clubs' or 'Diamonds', and ii) the rank of the card, which must be one of 2, 3, 4, 5, 6, 7, 8, 9, 10 (int), 'Jack', 'Queen', 'King' or 'Ace' (str). If an invalid suit or an invalid rank is passed, an AssertionError must be raised with the message invalid card.

Cards (Card) must at least support the following operations:

• If a card is passed to the builtin function repr, a string (str) must be returned that reads as a Python expression that creates the same card. If a card is passed to the builtin function str, a string (str) must be returned that describes the card in the form Ace of Hearts.

• The comparison operators ==, !=, <, <=, > and >= must compare two cards based on their rank alone, using the order in which the ranks are listed above (2 is the lowest rank and 'Ace' the highest). The suit plays no part in these comparisons, so two cards with the same rank are equal even if their suits differ.

Example

>>> card_1 = Card('Hearts', 'Ace')
>>> card_2 = Card('Spades', 'King')
>>> card_3 = Card('Clubs', 'King')
>>> card_1
Card('Hearts', 'Ace')
>>> print(card_2)
King of Spades
>>> str(card_3)
'King of Clubs'
>>> card_1 == card_2
False
>>> card_2 == card_3
True
>>> card_1 > card_2
True
>>> card_2 >= card_3
True
>>> card_1 < card_3
False
>>> sorted([card_1, card_2, card_3])
[Card('Spades', 'King'), Card('Clubs', 'King'), Card('Hearts', 'Ace')]
>>> Card('Trees', 7)
