Convert string object created from a class to list

In the task, I am trying to create an object of a deck of cards. The output is something like ['A of Hearts', 'A of Diamonds', 'A of Clubs', ...] and what I want is to convert the output to a list and get the length of the list.

After I created an instance from the class, I tried to get the type of the output, and it returns <class '__main__.Card'>.

I tried to convert the output, which should be a string, into a list by:

  1. Split the output string

  2. directly use list() function 

class Card:
    def __init__(self):
        self.suit = ["Hearts","Diamonds","Clubs","Spades"]
        self.value = ["A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"]
        self.cards = [] 

        for x in self.value:
            y = x + " of"
            for z in self.suit :
                aa = y + " " + z
                self.cards.append(aa)

    def __repr__(self): 
        return str(self.cards) 

cards1 = Card()

When I use the first function, it returns error 'Card' object has no attribute 'split'

When I use the second function, it returns error 'Card' object is not iterable

In this case what should I do? Many thanks

The structure of the class is not fine, but it works. You are returning an object, this object should have a method to return the string/list or you have to directly get the list as follow.

str1 = ''.join(cards1.cards)

If you are trying to just get the output in string form, then use an f string or a formatted string:

str1 = f"test1: {cards1}"
str2 = "test2: {}".format(cards1)
