Classes and lists

This shows a partial deck class using the Card class from earlier in this blog

from CardClass import Card

class deck:
    def __init__ (self):
        self.cards=[]
        self.populateDeck()

    def populateDeck(self):
        suits=["h","d", "c", "s"]
        for s in suits:

                card=Card(i,s)
                self.cards.append(card)

    def getDeck(self):
        return self.cards


def main():
    d=deck()
    myDeck=d.getDeck()
    for c in myDeck:
        print(c)

main();
    

        

here are the grade, and student classes.
