Tic Tac Toe with AI - Python Tutorial (Part 1)

In this video I explain how to create a tic tac toe game in python using a simple AI. This is an intermediate level tutorial and is extremely useful in enhancing your skills with python and gives a basic introduction to AI. This is a text based tutorial but everything used here can be implemented into a graphical version.

The code is clearly done by someone new to Python/coding, but it is still a nice Segway for me to get introduce to AI. And everyone need to start somewhere.
Just a short note to whoever is reading this, there is NO AI. This is pure algorithm. If player play at x1, y1 then computer play at x2, y2 kind of

i also appreciate that u just let ppl copy u and stuff. u explain so well and is just basically a type-along

[AaronProgZ]

Thanks for giving lots of room for us to code ahead by starting with empty functions.

[LemonChad]

Love the tutorials! Also, for the board, I used for a smaller and more efficient board

[firefennec]

i have made at least three games from u and have learnt a lot from ur channel. keep making these tutorials. ur rlly good

[turtlelife]

I come here to learn how to make an AI to implement into my already existing tic tac toe program...




And I find that you did almost everything the exact same, just better.

(I'll keep my existing code and put the AI into it while I'm following along, very convenient)

[braveleuterio]

Thank you! Your tutorial series is simple yet so informative.

[UlyssesOfOmaha]

The only issue I had so far with this was with the is_winner(bo, le) function. Python now makes us use a \ to split a statement onto another line. Other than that, dang man, you're a good teacher. I just did a 22-hour Python boot camp and this is a great follow up. I can't wait to dive into some of your other tutorials. On to video 2. . .

[shivamtyagi]

ur approach is very clear look really easy man...

[cafezinho]

hi welcome to the tutorial so basically just copy everything i write and gg

[NatCorry]

Just finished your Pygame Tutorial and can't wait to follow this. Your channel is gonna be huge

[MrDavidcanet]

Please dear expert. Is there somewhere a tic-tac-toe code that plays against itself. And learns from scratch . It progresses beyong human thought . It would be zero players.

[krishnans]

I just have some code fixes that make it way easier to write the code.


First, for your print board function (I used a 2D Array to make it easier):


def printBoard(bo):
for i in range(3):
if i == 0:
print(" ")
else:


for j in range(3):
print("|", end=" ")

if j == 2:
print(bo[i][j], end=" |\n")
else:
print(str(bo[i][j]), end=" ")
if bo[i][j] == " ":
bo[i][j] = 0
print(" ")


Next, for your isWinner function:


def isWinner(board, le):
for i in range(3):
if board[i][0] == le and board[i][1] == le and board[i][2] == le:
return True
if board[0][i] == le and board[1][i] == le and board[2][i] == le:
return True
for i in range(3):
if not board[i][i] == le:
break
if i == 2:
return True
for i in range(3):
if not board[i][2 - i] == le:
break
if i == 2:
return True
return False


It first checks rows and columns and then diagonals. These are just what I used to save myself from boring typing. Anybody who wants to copy this can do so, it does the same thing.

[coolpanda]

which algorithm is implement to solve this tic tac toe ?

[thiagoteixeira]

Is there any particular reason to use this:

run = True
while run:
run = false (when you don't want the loop to repeat)

instead of this, like you used in other loops:

while True:
break


?

[milanpaudel]

keep on doing what you are doing, keep uploading regularly, I sincerely believe this channel gonna be huge in near future.

[Janav_Gupta]

Its pretty easy to beat. I played it twice and won both times. If this was a perfect AI this should not have happened. Since tic tac toe is solved the AI should always either win or tie.

[saitech]

how to implement minimax algorithm here?

[Chartcombat]

I like this tutorial because you explain everything very clearly! Looking forward to part 2!
