As Kent pointed out, we need to see the error you are getting in order
to help. That usually shows up as a traceback. When I run your program I
get:
File "j:/python/tictactoe.py", line 53
movestowin=((0,1,2),(3,4,5),(6,7,8),(0,3,6),(1,4,7),(2,5,8),(0,4,8),(2,4,6))

IndentationError: expected an indented block
There are numerous other problems in your code. As you fix one error the
next will be revealed. For example when I fix the indentation error I
next get:
File "J:\python\tictactoe.py", line 124, in <module>
main()
File "J:\python\tictactoe.py", line 105, in main
computer, human = pieces()
File "J:\python\tictactoe.py", line 20, in pieces
human = X
UnboundLocalError: local variable 'X' referenced before assignment
Do you understand that variables must be assigned before reference?
Python does not know what X is.
So please report the specific error. Also try to determine what it means
before reporting it.
