Python Development Techdegree Graduate 9,410 PointsHey Ava! I am responding to these 2 questions:
"Now run it again, you will see that there are more rows than needed."
"And there is this problem A4: Add A3: Gum A4: Add A3: Dev"
In your dunder name statement at the end of game.py, try removing these 2 lines of code:
game.set_cards()
game.create_grid()
Here's why: you're creating an instance of the Game class, then you're calling the set cards and create_grid methods on the class. Then you call the start_game method after.
if __name__ == '__main__':
game = Game()
game.set_cards()
game.create_grid()
game.start_game()
Check out your start_game method. It sets the cards and creates the grid for you (you'll see create.grid() and set.cards() inside.)
You have the extra rows and the card issues because you're telling Python to set the cards, create the grid, and then do those steps AGAIN when you call start_game.
Remove those methods from the dunder name function, and you shouldn't have those issues anymore.
Once you do that and run the code again, you'll run into an AttributeError.
Traceback (most recent call last):
File "/home/treehouse/workspace/game.py", line 93, in <module>
game.start_game()
File "/home/treehouse/workspace/game.py", line 79, in start_game
guess1 = self.check_location('first')
File "/home/treehouse/workspace/game.py", line 67, in check_location
if guess.upper() in self.location:
AttributeError: 'Game' object has no attribute 'location
In your check_location function, check out this line:
if guess.upper() in self.location:
The error says that the Game object has no attribute called "location." To see why, look at the init method for your Game class:
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}')
All the locations are going into that self.locations list. As Steven said, it's self.locations (with an S at the end.)
After that fix, you will get this error once you enter the second card.
Traceback (most recent call last):
File "/home/treehouse/workspace/game.py", line 93, in <module>
game.start_game()
File "/home/treehouse/workspace/game.py", line 81, in start_game
if self.check_match(guess1, guess2):
File "/home/treehouse/workspace/game.py", line 56, in check_match
print(f'{card.location}: {card}')
TypeError: __str__ returned non-string (type set)
This is because of your str method in class Card. When you print a value wrapped in curly braces, it won't display properly unless it's formatted with an f-string. Like this:
class Card:
def __str__(self):
return f'{self.card}'
You should be all set now. I hope this helps!

But I did try running it and got this error on line 63: "AttributeError: 'Game' object has no attribute 'location'"
That occurs because the actual attribute is named locations (plural) instead of "location".

Full Stack JavaScript Techdegree Graduate 37,873 PointsOk Ava Jones... Several things here...
Regarding to the cards.py file this how I fixed it:
class Card:
def __init__(self, word, location, matched = False):
self.word = word
self.location = location
self.matched = matched
def __eq__(self, other):
if self.word == other.word:
matched = True
else:
matched = False
return matched
def __str__(self):
return self.word
As you can see I changed the 'matched' attribute definition. I did it in a way that it will have 'False' as a default value but it will change its value if the app requires so. In your case is always 'False'.
Then as you can verify I changed the eq method just take easy think without considering the syntax: 'if something is something then ... I get this...' You are comparing two things so: 'if something is equal to...'
Alright now the game.py file: (few things here)
1) You just need to write this inside the dunder main:
game = Game() game.start_game()
Since you are already calling all the methods you need inside game.start_game()
2) Inside the 'check_match' method you need to handle a possible IndexError (in case I try to guess A1 and A1 which is not possible).
def check_match(self, loc1, loc2):
cards = []
for card in self.cards:
if card.location == loc1 or card.location == loc2:
cards.append(card)
try:
if cards[0] == cards[1]:
cards[0].matched = True
cards[1].matched = True
return True
else:
for card in cards:
print(f'{card.location}: {card}')
return False
except IndexError:
print('You must select a different location please')
I believe that should be enough... Try for yourself and if you require further assistance I'll share the whole solution.
Cheers.
