Question

When I try to run my program in IDLE (the text editor i’m using at the moment, notepad ++ said indentation error and I don’t know why) it only does the code in __init__, which shows it’s been created into an object. But the line after that I tried to use the main method and it doesn’t do anything. I also changed it to a different method but that didn’t work either. Here’s my program:

import sys

class Main:
    def __init__(self):
        WinX = False
        WinO = False
        Turn = 'X'
        LastTurn = 'X'
        a, b, c, d, e, f, g, h, i = ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '
        PosList = []
        PosList.append(a)
        PosList.append(b)
        PosList.append(c)
        PosList.append(d)
        PosList.append(e)
        PosList.append(f)
        PosList.append(g)
        PosList.append(h)
        PosList.append(i)
        self.board = '+---+---+---+\n| ' + PosList[0] +' | '+ PosList[1] +' | '+ PosList[2] +' |\n+---+---+---+\n| '+ PosList[3] +' | '+ PosList[4] +' | '+ PosList[5] +' |\n+---+---+---+\n| '+ PosList[6] +' | '+ PosList[7] +' | '+ PosList[8] +' |\n+---+---+---+'
        print self.board

    def UpdateTurn(self):
        if LastTurn == 'X':
            Turn == 'O'
        elif LastTurn == 'O':
            Turn == 'X'
        LastTurn = Turn

    def WinChecker(self):
        if a and b and c == 'X' or a and d and g == 'X' or a and e and i == 'X' or g and e and c == 'X' or g and h and i == 'X' or c and f and i == 'X':
            WinX = True
        if a and b and c == 'O' or a and d and g == 'O' or a and e and i == 'O' or g and e and c == 'O' or g and h and i == 'O' or c and f and i == 'O':
            WinO = True

    def UpdateBoard(self):
        print self.board

    def Starter(self):
        while True:
            try:
                i = int(input(''))
            except TypeError:
                print 'Not a Number, Try Again.'
                continue
        i -= 1
        PosList[i] = Turn
        self.UpdateBoard
        self.WinChecker
        if Winx == True:
            print 'X Wins!'
            sys.exit()
        elif Wino == True:
            print 'O Wins!'
            sys.exit()
        self.UpdateTurn

s = Main()
s.Starter

I just (4 days) finished python’s own tutorial.

Answer 1

call Starter function like

s.Starter()

And also there might be an logical error The while loop below will be always true.

def Starter(self):
        while True:
            try:
                i = int(input(''))
            except TypeError:
                print 'Not a Number, Try Again.'
                continue
