How to make a print statement to test the game class?

Question

So I was just following the video for making a matching card game in python and the instructor would like us to make a print statement to test the game class. She would like us to print out the rows and columns of the matching game. I just am unsure of exactly how to do this. I kinda put what I thought it would be, but it does not seem to print out anything. I will put what I have for the classes below.

class Card:
    def __init__(self, word, location):
        self.card = word
        self.location = location
        self.matched = False


    def __eq__(self, other):
        return self.card == other.card

    def __str__(self):
        return self.card

from cards import Card
import random


class Game:
    def __init__(self):
        self.size = 4
        self.card_options = ['Add', 'Boo', 'Cat', 'Dev',
                            'Egg', 'Far', 'Gum', 'Hut']
        self.columns = ['A', 'B', 'C', 'D']
        self.cards = []
        self.locations = []
        for column in self.columns:
            for num in range(1, self.size + 1):
                self.locations.append(f'{column}{num}')

    def set_cards(self):
        used_locations = []
        for word in card_options:
            for i in range(2):
                available_locations = set(self.locations) - set(used_locations)
                random_location = random.choice(list(available_locations))
                used_locations.append(random_locations)
                card = Card(word, random_location)
                self.cards.append(card)
                for num in range(1, self.size + 1):
                    print(f'{column}{num}')


if __name__ == '__main__':
       Game()

While you have defined a set_cards method, you have not actually called it. Unlike __init__, the set_cards method is not run automatically when you create a new Game instance. You could add the line self.set_cards() to the end of the __init__ method to call the set_cards method.

In the set_cards method, used_locations.append(random_locations) should be used_locations.append(random_location) without the s.

In the innermost for loop of the set_cards method,

for num in range(1, self.size + 1):
    print(f'{column}{num}')

the value for column has not been declared. If the value of column was A, the set_cards method would print

A1
A2
A3
A4

sixteen times. To instead print the value of the cards, you could try something like

for column in self.columns:
    for num in range(1, self.size + 1):
        for card in self.cards:
            if (card.location == f'{column}{num}'):
                print(card, end='')
    print()

at the same indentation level as for word in card_options:. This will loop through the list of cards at each location and check if the card's location matches the current location. Using end='' in the print method will prevent the default line break. Using print() after all the cards in a row are printed will give a line break.
