TicTacToe and Minimax - python

I am a young programmer that is learning python and struggling to implement an AI (using minimax) to play TicTacToe. I started watching a tutorial online, but the tutorial was on JavaScript and thus couldn't solve my problem. I also had a look at this question ( Python minimax for tictactoe ), but it did not have any answers and the implementation was considerably different from mine.
EDIT: the code you will find below is an edit suggested by one of the answers (#water_ghosts).
EDIT #2: I deleted possiblePositions, as the AI should choose a free field and not a place from the possiblePositions (that wouldn't make it that smart while implementing minimax :) )
Now the code doesn't give out any errors at all and functions properly, but one small thing: the AI always chooses the next available field. For example in situations where i am i move away from winning, instead of blocking my win option, it chooses the next free spot.
If you're wondering what that elements dict is doing there: i just wanted to make sure the programm chose the best index...
Here is my code:
class TicTacToe:
def __init__(self):
self.board = [" ", " ", " ", " ", " ", " ", " ", " ", " "]
self.playerSymbol = ""
self.playerPosition = []
self.aiSymbol = ""
self.aiPosition = []
self.score = 0
self.winner = None
self.scoreBoard = {
self.playerSymbol: -1,
self.aiSymbol: 1,
"tie": 0
}
self.turn = 0
self.optimalMove = int()

print("___" + "___" + "___")
print(self.board[6] + " | " + self.board[7] + " | " + self.board[8])
def choice(self):
answer = input("What do you want to play as? (type x or o) ")
if answer.upper() == "X":
self.playerSymbol = "X"
self.aiSymbol = "O"
else:
self.playerSymbol = "O"
self.aiSymbol = "X"
def won(self):
winningPositions = [{0, 1, 2}, {3, 4, 5}, {6, 7, 8}, {0, 4, 8}, {2, 4, 6}, {0, 3, 6}, {1, 4, 7}, {2, 5, 8}]
for position in winningPositions:
if position.issubset(self.playerPosition):
self.winner = self.playerSymbol
print("Player Wins :)")
return True
elif position.issubset(self.aiPosition):
self.winner = self.aiSymbol
print("AI wins :(")
return True
if self.board.count(" ") == 0:
self.winner = "tie"
print("Guess it's a draw")
return True
return False
def findOptimalPosition(self):
bestScore = float("-Infinity")
elements = {} # desperate times call for desperate measures
for i in range(9):
if self.board[i] == " ":
self.board[i] = self.aiSymbol # AI quasi made the move here
if self.minimax(True) > bestScore:
bestScore = self.score
elements[i] = bestScore
self.board[i] = " "
return max(elements, key=lambda k: elements[k])
def minimax(self, isMaximizing):
if self.winner is not None:
return self.scoreBoard[self.winner]
if isMaximizing:

if self.board[i] == " ":

else:

for i in range(9):
if self.board[i] == " ":
self.board[i] = self.playerSymbol
bestScore = min(self.minimax(True), bestScore)
self.board[i] = " "
return bestScore
def play(self):
self.choice()
while not self.won():
if self.turn % 2 == 0:
pos = int(input("Where would you like to play? (0-8) "))
self.playerPosition.append(pos)
self.board[pos] = self.playerSymbol
self.turn += 1
self.drawBoard()
else:
aiTurn = self.findOptimalPosition()
self.aiPosition.append(aiTurn)
self.board[aiTurn] = self.aiSymbol
self.turn += 1
print("\n")
print("\n")
self.drawBoard()
else:
print("Thanks for playing :)")
tictactoe = TicTacToe()
tictactoe.play()
I come from a java background and am not used to this :(
Any help would be highly appreciated
I am open to suggestions and ways to improve my code and fix this problem.
Thanks in advance and stay healthy,
Kristi

Change this part, your implementation will return optimalMove even if it doesn't go inside the if statement, and optimalMove will not be assigned at that point, so put the return inside.
if score > sampleScore:
sampleScore = score
optimalMove = i
return optimalMove

optimalMove = 0 in play() and optimalMove = i in findOptimalField() are declaring two distinct variables, each of which is local to the function declaring it.
If you want multiple functions to have access to the same variable, you can use the global keyword, but that's generally considered a bad practice. It can make it hard to reason about the code (e.g. is var = x creating a new local variable or overwriting the value of a global?) and it doesn't stop you from accidentally using a variable before it's declared.
Since you're coming from a Java background, you can turn this into a class to get behavior more like what you expect, eliminating the need for globals:
class TicTacToe:
def __init__(self):
self.board = [" ", " ", " ", " ", " ", " ", " ", " ", " "]
self.playerSymbol = ""
self.playerPosition = []
self.aiSymbol = ""
self.aiPosition = []
self.score = 0
self.playerSymbol = None
self.aiSymbol = None
...
def drawBoard(self):
print(self.board[0] + " | " + self.board[1] + " | " + self.board[2])
...
def choice(self):
answer = input("What do you want to play as? (type x or o) ")
if answer.upper() == "X":
self.playerSymbol = "X"
self.aiSymbol = "O"
...
Each method now takes an explicit self argument that refers to the current instance, and you can use this to access any variables that belong to the class instance instead of a particular method. If you don't include self. before a variable, that variable will still be local to the method that declares it. In this case, the drawBoard() method won't be able to access the answer variable defined in choice().
You can create new self. variables in any of the class's methods, but the best practice is to initialize all of them in the __init__ constructor method, using None as a placeholder for variables that don't have a value yet.

I am posting this as an answer, just in case somebody in the future stumbles upon the same problem :)
the main issue i encountered (besides my bad programming style) is that i forgot to update the contents the lists playerPosition and aiPosition.
You can review the rest of the changes in the working code:
class TicTacToe:
def __init__(self):
self.board = [" ", " ", " ", " ", " ", " ", " ", " ", " "]
self.playerSymbol = ""

Python: Create Dict in function a and call it in function b

i have a problem with creating a dict in python.
In my mainloop i call function 1 which should creat an empty dict.
function 1 calls function 2.
function 2 calls itself (loop through a game tree)
but i can not use the dict i created in f1.
and it is not possible to pass it as agrument.
i would like to have the dict globaly accessible
def f1(): # function 1
#test_dict = {} # this needs to be global scope
#test_dict["key"] = "value"
test_dict["key2"] = "value2"
print (test_dict)
f2()
def f2(): # function 2
# here starts a loop that calls f2 again and again -> global dict is needed
# dict needs to be created
print (test_dict)
test_dict = {} # only works without errors when i create it before calling f1
test_dict["key"] = "value"
f1()
Here is my "real" Code :)
The >>MinMaxComputerMove<< need to edit the dict.
but at the end of a nood i cant pass it because the for loop just goes on.

The "return value" answer is:
def f1(test_dict): # function 1
#test_dict = {} # this needs to be global scope
#test_dict["key"] = "value"
test_dict["key2"] = "value2"
print ('In f1 {}'.format(test_dict))
f2(test_dict)
return test_dict
def f2(test_dict): # function 2
# here starts a loop that calls f2 again and again -> global dict is needed
# dict needs to be created
print ('In f2 {}'.format(test_dict))
return test_dict
test_dict = {} # only works without errors when i create it before calling f1
test_dict["key"] = "value"
test_dict = f1(test_dict)
which gives output of:
In f1 {'key2': 'value2', 'key': 'value'}
In f2 {'key2': 'value2', 'key': 'value'}
But at some level, you probably want to put some of this into a class and then have test_dict as a variable within the class. That allows f1 and f2 (assuming they are class methods) to access the class variable without passing it as a parameter to the two methods.
class Example:
def __init__(self):
self._test_dict = {}
self._test_dict["key"] = "value"
def f1(self): # function 1
self._test_dict["key2"] = "value2"
print ('In f1 {}'.format(self._test_dict))
self.f2()
def f2(self): # function 2
print ('In f2 {}'.format(self._test_dict))
example = Example()
example.f1()
Below is a very simply version of what your script is attempting. You need to consider what your function parameters should be (what is passed to the function), as well as what your function should be providing at the end of its execution (given to you with the return statement). This way you can manipulate objects without having to keep everything in global scope, and you can avoid having to initialize every conceivable variable at the start of the routine.

Is this following the MVC infrastructure? How to know if it fits the MVC structure or not? Thanks. Does we have to put each model,view,and controller in different module for it to be described as following the MVC structure?
First off the program is not really object oriented. View is instanciated every time when the game state has to be displayed just to call the one and only method. Classes with just the __init__() and one other method are a code smell because, like in this case, it's just a function crammed into a class for no good reason. The same can be said about Control — also just the __init__() and one additional method that get's called exactly once right after instanciating the object and directly after the call the object isn't used anymore.
Taking those ”fake” classes and considering the amount of static methods it seems you are under the impression classes automatically lead to object oriented programs — they don't. And there is nothing wrong with using functions instead of artificially introducing unnecessary complexity with classes that are just syntactically classes. Functions are objects too in Python, so when you have a display function it's okay to pass that around as „view” part of an MVC pattern. It's a callable object.
Which brings us to the MVC question: Supposing Player is the model then it should not interact with the user by printing stuff. Display and input is for the view to handle. So Control isn't a controller because the function in disguise also heavily interacts with the user via print() and input().

This line right is one problem:
a=self.dealer.hand.append(DeckofCards.deal(DeckofCards.shuffledeck))
append returns None (regardless of what you append), so a will be None
DeckofCards refers to the class object, not an instance of the class. You probably want to use self.deck instead of DeckofCards.
x==Card('S','A'): isn't going to work either. You haven't defined __eq__ for the Card object, so comparisons don't work (you'll always get False).
The shuffledeck attribute only exists for instances of DeckOfCards, change DeckOfCards.shuffledeck to DeckOfCards().shuffledeck.

continued trouble with classes in python 3.2

In the below code, it is working at first but when I want it to tell me what card number the dealer has it is returning some sort encrypted stuff that I don't understand.
[<__main__.Card object at 0x025A4E50>]
How do I get this to return the corresponding card number?
Also someone said that I may need to use __eq__ when comparing things as opposed to the way that I currently am could someone explain why, and also how to use __eq__ ?
Below is the code for the program that I am trying to get to work, it is a blackjack game.

Print the card instead of the list of card objects and give the card a decent __str__ method to display itself human-readable. Instead of
print(self.player.hand)
try this:
for card in self.player.hand:
print(card)
and in class Card insert this:
def __str__(self):
return '%s%s' % (self.number, self.suit)
Concerning your question about the __eq__: An objects __eq__() method gets called whenever it gets compared for equality using the == operator. Without such a method, two objects are only equal if they are the same object. So in your cards you might want to have sth like this:
def __eq__(self, other):
return self.number == other.number and self.suit == other.suit
When you use str() on a Card object it calls an inherited __str__ method which will print out the class name and address of the object. What you call encrypted is the address of the object. If you want to print out something different, override the __str__ method in your class. For example:
class Card(object):
def __str__(self):
return "Card " + self.suit + " " + self.number

Recording a win or loss in a game of craps

So I have to create a game of craps that takes into account bets for an assignment. So far, my code works in that the dice rolls are correct and other little tidbits the assignment called for. But now I don't know how to record each game as a win / lose for the player or computer so that the pot can be added to the winner's money. I realize that my code is half doe, isn't finished, and doesn't run as is, but I just seriously need some help from someone. Please and thank you. Here are more specific directions on my assignment:
http://www.ics.uci.edu/~kay/courses/i42/hw/labA.html
import random
def craps():
print("Welcome to Sky Masterson's Craps Game")
handle_commands()
def handle_commands(): # Collection -> Collection (plus interaction)
""" Display menu to user, accept and process commands
"""
playerInitial = 500
compInitial = 500
MENU = "How much would you like to bet?: "
while True:
bet = float(input(MENU))
if bet <= playerInitial:
human_game()
elif bet > playerInitial:
print("Sorry, you can't bet more than you have")
def handle_commands2():
MENU2 = "Would you like to play again? (y or n): "
while True:
response = input (MENU2)
if response=="y":
counter = counter + multipleGames()
elif response=="n":
while ( counter < 2000):
roll = random.randint(1, 6) + random.randint(1,6)
updateCount(roll)
counter += 1
print ("Thank you for playing." + "\n" + "\n" + "Distribution of dice rolls: " + "\n")
return
else:
invalid_command(response)
def invalid_command(reponse):
"""print message for invalid menu command.

print("Sorry; '" + response + "' isn't a valid command. Please try again.")
def play_game():
"""prints shooters roll results
"""
diceRoll = 0
roll = random.randint(1, 6) + random.randint(1, 6)
updateCount(roll)
diceRoll = diceRoll + 1
point = 0
print("The roll is " + str(roll))
response = (roll)
if response== 7 or response== 11:
print("Natural; shooter wins" + "\n" + "Thank you for playing")
handle_commands2()

handle_commands()
while (secondRoll !=point) and (secondRoll != 7):
secondRoll = random.randint(1, 6) + random.randint(1, 6)
updateCount(secondRoll)
diceRoll += 1
print("The roll is " + str(secondRoll))
handle_commands()
if secondRoll== point:
print ("Made the point; shooter wins." + "\n" + "Thank you for playing")
handle_commands2()
elif (secondRoll == 7):
print ("Crapped out; shooter loses." + "\n" + "Thank you for playing")
handle_commands2()
return diceRoll
def multipleGames():
gameCounter = 0
while (gameCounter <= 2000):
print("Your game: ")
gameCounter += play_game()
print("\n")
print("Computer's game: ")
gameCounter += play_game()
print( "\n")
return gameCounter
def updateCount(point):
count =List[point] + 1
List[point] = count
List = {2:0, 3:0, 4:0, 5:0, 6:0, 7:0, 8:0, 9:0, 10:0, 11:0, 12:0}
def human_game():
playerInitial = 500
compInitial = 500
while True:
play_game()
if
playerInitial += bet
compInitial += bet
counter = 0
counter = counter + multipleGames()
playerInitial -= bet
craps()
for point in List:
print("%2d" %(point) + ": " + "%3d" %(List[point]) + " " + "(" + ("%2d" % (int((List[point])/2000*100)))+ "%" + ")" + " " + ("*" *(int((List[point])/2000*100))))
Use classes:
import random
class Human:
def __init__(self):
self.name = 'Human'
self.wins = []
self.losses = []
self.bets = []
self.total = 0
class Computer:
def __init__(self):
self.name = 'Computer'
self.wins = []
self.losses = []
self.bets = []
self.total = 0
class Game:
def __init__(self):
self.rolls = []
self.currentPlayer = None
def roll(self):
self.rolls.append(random.randint(1, 6))
if __name__ == '__main__':
human = Human()
computer = Computer()
game = Game()
game.roll()
print games.rolls
I won't code all of it for you, but using classes will make things much simpler.
