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)

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)

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 :)

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?

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 ?

@CodeCoachh

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!

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.

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.
