Tic Tac Toe in python

Info
This Little Script works with python 3.4 and Tkinter.
It is only 37 lines long, but very fast and has a small size.

Code:

from tkinter import *;turn=None
class pButton(Button):
    def setty(self):self.state=None
    def SET(self,what):
        if what in("X","O"):
            self.state=what
            if what=="X":self.config(bg="light green")
            else:self.config(bg="tomato")
            self.config(text=self.state)
        else:print("error")
class Main:
    def __init__(self):
        self.root=Tk();self.root.title("Tic Tac Toe");self.root.geometry("180x180")
        self.b=[None,None,None,None,None,None,None,None,None,None]
        column=0;row=1
        for i in range(0,9):
            self.b[i]=pButton(self.root,text="-")
            self.b[i].setty()
            self.b[i].grid(row=row,column=column,pady=5,padx=5)
            self.b[i].config(width=5,height=2)
            self.b[i].bind("",lambda event, arg=self.b[i]: self.push(event, arg))
            column+=1
            if column>2:column=0;row+=1
        global turn;turn="X"
        self.L=Label(self.root);self.L.grid(row=4,column=1);self.L.config(text="{Turn of X}")
        self.root.mainloop()
    def push(self,event,pButton):
        global turn
        if turn=="X":pButton.SET(turn);turn="O";self.L.config(text="Turn of O")
        elif turn=="O":pButton.SET(turn);turn="X";self.L.config(text="Turn of X")
        self.debug()
    def debug(self):
        for i in ("X","O"):
            for x,y,z in [0,1,2],[3,4,5],[6,7,8],[0,3,6],[0,4,8],[2,4,6],[1,4,7],[2,5,8]:
                if self.b[x].state==i and self.b[y].state==i and self.b[z].state==i:self.L.config(text=i+" wins"),self.L.config(bg="yellow")
            else:pass
main=Main()
