Create a list of playing card specs and store in a file [solved]

[prince99]

Write a program that creates a list of card objects and prints out the cards grouped by suit and in rank order within each suit. The program should read the values for the list of cards from a file, where each line in the file specifies a single card with the rank and then the suit separated by a space. Hint: sort the list first by rank, and then by suit.


thanx

Ok. It's awesome for me to see the progress that you are making. Learning does happen when you are willing to experiment with examples.
This forum is here for this reason. Here are two more functions so you can see how files are used. Ultimately, we don't use files for storage so much anymore, now that SQL databases are free tools for data storage.

rank_desc = {1:"Ace", 2:"Two", 3:"Trey", 4:"Four",
             5:"Five", 6:"Six", 7:"Seven"}    # describe each rank in a dictionary

class PlayingCard:
    def __init__ ( self, rank, suit ): # Creates a card.
        self.rank = rank
        self.suit = suit
    def getRank(self): #Returns the rank of the card.
        return self.rank
    def getSuit(self): # Returns the suit of the card. 
        return self.suit
    def BJValue(self): # Returns the 'Blackjack value' of the card (Ace;1, Face card:10) 
        return min(self.rank, 10)
    def __str__(self): # Returns a string naming the card. For example: 'Ace of Spades'
        return "The %s of %s is worth %d Blackjack" %(rank_desc[self.rank],
                                                 suit_desc[self.suit],
                                                 self.BJValue())
