Help?

Question

Hi, i have a code, imports images, you can read it if you want:
import os
import pygame
from pygame.locals import *

pygame.init()

WasItX = True
Cells = ['', '', '', '', '', '', '', '', '']

screen = pygame.display.set_mode((600, 600),0,32)
background = pygame.image.load("bg.png").convert_alpha()
imgX = pygame.image.load("x.png").convert_alpha()
imgO = pygame.image.load("o.png").convert_alpha()
screen.blit(background, (0,0))

pygame.display.update()

x, y =500, 300

def cellNum(x,y):
if (x<200 and y<200):
return 1
if (x>200 and x<400 and y<200):
return 2
if (x>400 and y<200):
return 3
if (x<200 and y>200 and y<400):
return 4
if (x>200 and x<400 and y>200 and y<400):
return 5
if (x>400 and x<600 and y>200 and y<400):
return 6
if (x<200 and y>400):
return 7
if (x>200 and x<400 and y>400 and y<600):
return 8
if (x>400 and y>400):
return 9
return 0

def getImg():
global WasItX
if WasItX == True:
WasItX = False
return imgO
else:
WasItX = True
return imgX

def fillArray(cellNum):
if WasItX == True:
Cells[cellNum-1] = 'x'
else:
Cells[cellNum-1] = 'o'
print(Cells)

while True:
for event in pygame.event.get():
if event.type == pygame.MOUSEBUTTONDOWN:

x, y = pygame.mouse.get_pos()
print(x, y)

if cellNum(x,y)==1:
screen.blit(getImg(), (0, 0))
pygame.display.update()
fillArray(1)
elif cellNum(x, y)==2:
screen.blit(getImg(), (200, 0))
pygame.display.update()
fillArray(2)
elif cellNum(x, y)==3:
screen.blit(getImg(), (400, 0))
pygame.display

Answer 1

Looks like it got out of maximum, i did give it clear description.

Answer 2

Look its in destruction, in future its gonna be a tic tac toe, it returns values of the "tiles" in game, returns numbers(1 to 9) by getting their x and y.
and not gonna tell all the functions, just gonna skip to saying i want it to dont let me reassign a x to o or o to x if its been already assigned to x or o

Answer 3

Thanks, but can you give a bit more clear explanation?

Answer 4

I have no redundant input, like you know what i mean? and there are no arbitrary inputs.
