my man... this was a great video. I love how you lay this out. I've tried watching other basic python projects but have trouble following other people's thinking, but your's came really intuitive to me so THANK YOU. Gonna be watching more of your vids for sure. Thanks again!
For those who found the bug that appears when the last input is a winning move, and it displays both the Win AND Tie text, this should fix it. If you add a "exit()" command inside of the "def checkWin()" segment, it should work itself out: def checkWin(): if checkDiagonal(board) or checkHorizontal(board) or checkRow(board): print(f"The winner is {winner}") gameRunning = False exit() Since the gameRunning loop checks for a Win BEFORE it checks for a Tie, you only have to apply this to the "def checkWin()" segment :)
@@denisem1951 I don't think that the "exit()" line will literally exit the shell, only end the code. You can try "quit()" as well :). That should work too, although I haven't tried it.
after dealing with some hiccups throughout this tutorial. I noticed there were some indentation errors for me, but overall I got it to work in the end! Thank you for your tutorial as this was my first ever project and I am getting a grasp on the terminology.
This was really fun to do, thank you so much! Do you think you could possibly do some Python tutorials for complete beginners? The way you teach and explain what you're doing is the best and would love to see it in Python tutorials 😆
Something is false I think. If you use a number which is already taken, the player switch. So one person can play two times if the other took a number which has alraedy been used (sry for bad english but hope y'all understand)
the way to fix that is to loop the players input until it meets the condition. in that way if you input the same number it loops and it asks the input again, then if it meets the conditon ,the loop breaks and then the computer will proceed def player_Input(board): while True: inp = int(input("Enter number from 1-9: ")) if inp >=1 and inp
Obviously you are coming from JS , in python we do board = ["-"] * 9 and you don't need to pass board to the function cause it's on global scope and functions defined after that has access to the board.
Hey when the game ends with a horizontal or diag or row as the last input (no "-" on the board remaining but last input made one of 3 lines) it still says that it's a tie despite clearly being a win for one of the players. How can I fix this?
in the function userInput you should call it again recursively in the else statement like this: def playerInput(board): inp = int(input("Select a spot 1-9: ")) if board[inp-1] == "-": board[inp-1] = currentPlayer else: print("Oops player is already at that spot.") playerInput(board) Because if the user chooses a number which was already chosen it will display the message and then go to the next player, but we want the same user to try again in another spot, not switch players after an error
I m wondering how to get the game to reset after the win. I was thinking that after gamerunning = false you could break the loop... but doesn't seem to work for me... any tips?
Thank you for this video!!! I have to do a project for my programming class and this has helped me understand a ton!! I have to use Matlab… I think it’s doable as long as some changes are made for the language… do you think this would be a possibility?
def start_game(): mode = input('Choose mode pvp/ai: ') if mode == 'pvp': run_pvp() else: run_ai() def run_pvp(): while game_running: print_board(board) player_input(board) check_win() check_tie(board) switch_player() def run_ai(): while game_running: print_board(board) player_input(board) check_win() check_tie(board) switch_player() ai_player(board) check_win() check_tie(board) start_game() this would be a way to handle both computer and player. *note i changed some function names to my liking but should be clear in reference to the tutorial
Great video, thank you very much :) however i have a slight problem. When the board is completely full and either player wins on the last move, it prints out above the board that the winner is ___ and bellow the board it says that it is a draw. Do you have the same problem od did I make a mistake? Thanks
You didn't make a mistake! If you add a "exit()" command inside of the "def checkWin()" segment, it should work itself out: def checkWin(): if checkDiagonal(board) or checkHorizontal(board) or checkRow(board): print(f"The winner is {winner}") gameRunning = False exit() Hope this helped!
This is a wonderful video, but in the case that the last move results in a win then it would print both the winner and also that it is a tie, what is a different way you could get around this?
It was a really nice and informativ Video, I learned a lot from you! But I found 1 small bug. If you choose a number that was already picked, the Computer atomatically just picks another spot so hes in the lead. But i fixed it with just one line: Where you printed the line "Oops player already in that spot" Write underneath switchPlayer() And your done it just switches back to you. I hope you know what I mean by that.
i have a few problems when i was copying the code 1. the board was printed twice in the beginning 2. when i put an occupied space as X, the current player next turn would be changed to O 3. it says there is a problem at "position = random.randint(0, 8) and i dont know how to fix this
Hi, i've found 2 big problems...first if you pplay against the computer he can't win, second if then computer win the game continue and if you win the game give you the win and when the board is full it's a tie. If you play against yourself using this combination of number (1-2-3-4-5-6-8-7-9) the game give you the win but it's a tie and immediately after the game print that it's a tie because the board is full...I'm trying to find where the problems, did you had already found them?
if you combine the checkTie def with the checkWin def... example: def checkWinOrTie(board): global gameRunning if checkHorizontal(board) or checkRow(board) or checkDiag(board): print(f"The winner is {winner}!") gameRunning = False elif "-" not in board: print("It is a Tie!") gameRunning = False ...I think that should fix the problem with the tie print
Hi coach! I was testing your program and i found an error. When you insert a number that is already occupied, it stills switching the turn and enables the x or o user to make 2 moves in a row. Do you know how can i solve it. Thanks for your help :)
@@AlExItOXD409 I did player input like this and it works fine (no switching error): def player_input(board): while True: try: inp = int(input("Enter a number 1-9: ")) if 1

Nice video thank you , only had to change it on playerInput , because if there was a "oops blablabla.." it would switch to the next player , so you can fill the rest of the grid with only O or only X if you want : def playerInput(board): while True: user_input = int(input("Enter a number 1-9: ")) if user_input >= 1 and user_input
thanks, very nice and clear about contents the only thing I was curious to know is how can we make computer to try to win rather than throwing random input
There are a couple algorithms which can be implemented to improve the computer. The most common is the mini max algorithm and I could potentially make a video adding that feature to the game.
After print("Oops player already on that spot") executes, the computer keeps playing until the game ends, which crashes it. I added the switchPlayer() function right below the print. That solved the issue.
HELP great vid i copied it perfectly but im jw how do i get in the terminal mine isnt like urs also i cant run the program it says error "cant find __main__" i put this in a new file im 1 week into coding so i probably didnt do something very basic
Oddly I'm getting "oops player is already in that spot when entering 1. 2-9 is cool though. There's a dash in the 1 position in the code just like 2-9. The computer is able to use position 1 though.
I've been told to stop watching tutorials and build projects without help by so many programming RUclipsrs and I follwed the advice, but I just couldn't make the Tic Tac Toe game. No matter how hard I tried, I just couldn't make it happen. I feel so stupid and I have so many doubts whether I should continue or not.

Hi @coachcode for the code board(inp-1) == "-" at 8:02 of the video I understand that it is to check if the position picked on the board by the player is empty. But why is there -1 from inp? Shouldn't it be just board(inp) to check the availability of the position picked by the player on the board?
Basically, a program counts a list like 0, 1, 2, 3, 4 and we usually count a list like 1, 2, 3, 4, 5. So when the person inputs a 6 we want to convert it to a computer number which is five or (input-1). (hope this helps)
@@262626VJ26 the indexes in the list go from 0 to 8 but the numbers you input go from 1 to 9 so you have to subtract one from the input to get the correct index
Basic multiplayer requires a lot more code and gets pretty advanced but maybe if I have a lot of time over a long weekend I can try and learn how to do it! In the mean time, I just published a video creating an unbeatable AI to play against in this tic tac toe game
Hi great tutorial really helpful. I was following your code and I get stuck when you create the function checkWin, when i create my if loop and try to call the other functions that check for rows, columns and diagonally I get an error message that those 3 functions dont exist. I cant figure out why this could be
8:28 That [inp-1] is to find the index(Since the player input starts at 1 and the board index starts at 0 we sub the 1) after that we assign the player input to the board accourding to the index. Therefore it is Board[index] = playerInp.
Within the scope of the function any variable is classified as local (not existing outside the function) unless passed as a parameter or declared as global.
How can we make it so the game ends after someone wins? I've tried a few things but can't come up with It myself. As of now, after a player wins, the game continues and it ends in a tie.
Here we are checking if the position in the board the user inputted is equal to “-“ to see if that is an empty position as the array board was initialized containing “-“ and input -1 is the index of the position we must check.
That is because in programming counting always starts at 0. In this game we represented the game board as an array of strings with each index representing a spot on the board - so in order to set a random position all we have to do is generate a random number excluding 9 as 8 is the max index in the list. I hope this made sense!
board = ['-', '-', '-',
'-', '-', '-',
'-', '-', '-']
currentPlayer = "X"
winner = None
gameRunning = True

Thanks for this, ive been learning python for a few weeks and i did a few projects and yet i still had some trouble with the basics...
this is a very clear and concise tutorial
in the function userInput you should call it again recursively in the else statement like this:
def playerInput(board):
inp = int(input("Select a spot 1-9: "))
if board[inp-1] == "-":
board[inp-1] = currentPlayer
else:
print("Oops player is already at that spot.")
playerInput(board)
Because if the user chooses a number which was already chosen it will display the message and then go to the next player, but we want the same user to try again in another spot, not switch players after an error

I don't understand. How is possible to equal board[inp - 1] = current_player. But current_player variable is a string type, and inp - integer
8:28
That [inp-1] is to find the index(Since the player input starts at 1 and the board index starts at 0 we sub the 1) after that we assign the player input to the board accourding to the index.
Therefore it is Board[index] = playerInp.

why do you send the board variable in the arguments if its already global? wont it be otherwise accesible?
Within the scope of the function any variable is classified as local (not existing outside the function) unless passed as a parameter or declared as global.
How can we make it so the game ends after someone wins? I've tried a few things but can't come up with It myself. As of now, after a player wins, the game continues and it ends in a tie.
To make the game end you would have to break out of the game loop following a win or a tie.
@@CodeCoachh And how would we do that? where would we have to change the code?
hi just wanted to ask, what does
"-1" in board[inp-1] == "-" ?
Here we are checking if the position in the board the user inputted is equal to “-“ to see if that is an empty position as the array board was initialized containing “-“ and input -1 is the index of the position we must check.

def computer(board)
why do you set the position that the computer can pick from 1-8 only ? why not 1-9 ?
That is because in programming counting always starts at 0. In this game we represented the game board as an array of strings with each index representing a spot on the board - so in order to set a random position all we have to do is generate a random number excluding 9 as 8 is the max index in the list. I hope this made sense!
@@CodeCoachh Thank you for the explanation, but if that's the case, why is it not 0-8?
what is the theme that you are using
I do not really remember which theme it was. It was a while ago on a different laptop. Sorry I could not be more helpful.
