Obrigado!😁
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!
thanks bro
Excellent; I will return to this one once I finish my weekly assignments. Great video!
so damn awesome my man. i loved it all the way. my first big project in learning python. thanks for the tutorial.
you make it so easy to understand, but actually making it and developing the program is a whole different story!
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 😆
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...
thanks man im a beginner and ive seen like 3 tutorials and yours is the most easy to understand.
Glad I could help, thanks for the support!
You explained this better than how my professor explain python... thank you!!
Great beginner-friendly tutorial on how to build a simple project like TicTacToe!
Glad it was helpful!
This was really great ..your explanations and steps are great! excellent work. Thank you so much for this video.
You're very welcome!
this is a very clear and concise tutorial
Most simplest video on yt, Thanks a lot.
great video looking forward to seeing another project thank you for all the help.
Well explained and easy to understand . Great!!!
The best lecture to me as a beginner ,thanks.
the most easy way and literally easy to understand. The best tutorial
Thank you!
The video is awesome, quite enjoyed it!
Awesome video dude, very helpful
The best tic tac toe tutorial.
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?
Thank you for giving me a good lecture, sir.
thanks this was a tremendous help!
thanks man it was so much helpful
Thank you for a clear explanation. You are the best!!!
thanks!
by far the best workflow for Tic Toe Toe
very nice video, good explanation and well understood . Thank You
Totally worth it!
I will like following you up till I fully understand programming.
such an amazing video bro
thank you !!!!!! nice and clear.
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?
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 :)
instead of exit() is there a different code that will just end the shell instead of exiting out of it?
@@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.
WOW! how cool!
tnk u so much, it very helpful
thank you! this makes more sense than the free code camp one
Thanks man!
Thank you so much life save!
When the player inputs an invalid input (e.g. if 10 is inputted) it switches immediately to the next player so is there any way to fix that
amazing, thank you
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)
brilliant video really helped me out thanks alot
I am glad I could help!
Great Explanation and video, i was just wondering is there a way to end the code if someone wins
Thank you!
thank you so much exelent video
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.
i dont know why but when ever i put in a number it shows oops player has taken the spot pls help
great tutorial it saved my term
Glad it helped
Great tutorial
while running the "gamerunning func at 9:30 , its saying ""bool object is not callable""////--> how do we solve this??
Let me know what you guys think!
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 :)
hi how can we make this using A* algo? would really appreciate if you could teach it
@@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
@@thereverend01 Planning on doing this tutorial before the end of the summer!
awesome tutorial!
Thank you!
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
I would make sure the functions are spelled the same in both places - sorry for the late reply
keep going bro
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!
Its Amazing
there is one bug in this code and I'm not able to figure out how to correct it. if player x wins still o takes the turn and then winner is declared
How do I create the option to replay the game instead of exiting?
Great video!!!!!!!!!!
❤❤❤❤
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?
I’m sure it can be done tic tac toe is pretty simple.
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
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.
I’m new to coding does this have a list and a function?
When I run my python code on visual studio code the numeric keys are not working why is that?
Enter your name 1-9: .my numeric keys aren't working in this line why?
hi, how can i make it on 3 wins?
what is the website called?
What is your vscode theme?
I tested it but it broke at the change player help
using this as a base, how could I make a "star menu" at the beginning where you can choose if you want to play against the computer or a friend?
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
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)
@@d1ylor266 so you mean like last number in that list?
@@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
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?
yeah same here ,after winning the game , the game is not resetting automatically. gameRunning = False is also not working for me
I tried running it @9:39 but it keeps telling me “oops player is already in that spot” but there’s no player. I need help
Best tic tac toe tutorial on UA-cam
Thx mon
great video thanks alot:)
Glad you liked it!
i didnt get how the "global" works, both with "global currentPlayer" and "global winner"?
thanks for code
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
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.
I didn't understand the "board[inp-1]" thing in the function of playerInput.
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.
Yes, some others pointed out my flaw in my logic here I’m glad you were able to figure out my error!
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
It’s hard for me to debug considering I do not have ur code but 2 sounds correct and for 3 I would double check you imported random.
@@CodeCoachh i'll check it later today and import random, thanks
Thanks
can you code tic tac toe which is multiplayer and vs computer , with scores and time
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
Great vid coach… I was wondering how to code it so that the bot doesn’t always win… can u make a vid on that?
Was up Nate! Check my response on the minimax video!
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
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 understood most of this but why is the -1 place in the [inp-1 ] ?
if inp >= 1 and inp
Because the board starts at index 0, so it goes from board[0] up to board[8] while we asked the user to choose a number between 1-9
to avoid index out of range
I want to create a GPS and printing application
Why is mine not working? NameError: name 'checkWin' is not defined
board = ["-", "-", "-",
"-", "-", "-",
"-", "-", "-"]
currentPlayer = "X"
winner = None
gameRunning = True
#printing the game board
def printBoard(board):
print(board[0] + " | " + board[1] + " | " + board[2])
print("---------")
print(board[3] + " | " + board[4] + " | " + board[5])
print("---------")
print(board[6] + " | " + board[7] + " | " + board[8])
print("---------")
# take player input
def playerInput(board):
inp = int(input("Enter a number 1-9: "))
if inp >= 1 and inp
thanks g😃
on line 87
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?
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.
My python isn't showing the board and it Python 3.12.0
does anyone have a fix for computer making one extra move after I win the game? The code in the github does it as well
I did some minor tweaking in the code but if you still want it I can update my code to add a computer to it and fix it
def computerPlayer(board):
while currentPlayer == 'O' and gameRunning:
pos = random.randint(0, 8)
if board[pos] == "-":
board[pos] = 'O'
switchPlayer()
you need to add "and gameRunning" to the while statement and it fixes it
color theme name?
so with this im finding that if you choose a spot that is already taken, it still switches currentPlayer variable and skips your turn
You can fix this by removing switchPlayer() from the while cycle and put it in the playerInput under the if statement
Your check diagonal when its from top left to bottom right is incorrect.
Cant run it again please help
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
How to loop the game
