Unknown_error [PYTHON]

[Gogetakao]

So recently I have been making an AI in tic tac toe game.
unfortunately it is giving me headache by this error.

The current situation of board is...
EMPTY   EMPTY   X

EMPTY   EMPTY   0

EMPTY   EMPTY   EMPTY

The squares starts from 1 to 9.
Which square do you want to move?
9
The current situation of board is...
EMPTY   EMPTY   X

EMPTY   EMPTY   0

EMPTY   EMPTY   X

yes
Traceback (most recent call last):
  File "D:\Softwares\Developing\Python\Installation\programs\TicTacToePractical.py", line 147, in <module>

  File "D:\Softwares\Developing\Python\Installation\programs\TicTacToePractical.py", line 67, in board_update
    temp = temp - 1
TypeError: unsupported operand type(s) for -: 'list' and 'int'

The original code of the function

def board_update(move,player):  #Tested, and disapproved.
    '''Updates the board with respect to input given by the user'''
    temp = move
    global board
    global used
    global X
    global O
    if player == 'X':
        board[move-1] = 'X'
        used = used + [move]
    else:
        temp = temp - 1
        board[temp] = 0
        used = used + [temp]

It gives you the exact error in words: you can't do list - int.
The real question is why you are using a list and expecting it to be an int, and that only you know, since you didn't post the relevant code.

The variable move has been initialized as an into.

Also since temp = move
The variable temp with also be int.
So move -1 gives us an int.

Still I am getting the error

Tried debugging the script and seeing the actual values at run time? If you cannot use an actual debugger, then at least print the values at the problematic spot. You might find that what you think is an int is a list containing an int element.

The variable move has been initialized as an into.

Also since temp = move
The variable temp with also be int.
So move -1 gives us an int.

Still I am getting the error

a = 1
a = "asd"
a = [1, 2, 3, 4]

What is the type of a? Whatever it is set to!

You can be stubborn, or you can actually look at your code and find out why move is a list and not an int...

It was converting int into list unexpectedly!I used the print statement to debug the code.
It printed as follows:
int
int
int
list
Type error

Anyways I solved it,
I used the if else:

if type(x) == list :
perform list functions
else:
perform integer functions

I don't exactly have the syntax, because it is my rule.I work on a project for atleast 3 days, at fourth day I hands off the job.
