'Python Turtle tic-tac-toe board letters keep disappearing
I've made a tic-tac-toe game in python using python turtle. I've made it so that when you click on a square on the board, a letter is placed there, and then the computer places a letter onto the board. However, when the player places a letter on the board and the computer places a letter on the board, a split second later, the letters completely disappear from the board.
Here's the code in which the problem lies:
def printTurtleBoard():
pensize(10)
speed("fastest")
hideturtle()
screen.setup(500,500)
penup()
X = -150
Y = -50
goto(X,Y)
pendown()
for i in range(3):
for i in range(4):
forward(100)
right(90)
penup()
forward(100)
pendown()
for i in range(4):
forward(100)
right(90)
penup()
forward(100)
pendown()
for i in range(4):
forward(100)
right(90)
penup()
Y = Y + 100
goto(X,Y)
pendown()
randomY = random.randint(0,2)
randomX = random.randint(0,2)
global letterO
def letterO():
if randomY == 0 and randomX == 0:
drawer.penup()
drawer.goto(-100,40)
drawer.pendown()
drawer.write("O", align="center",font=("Arial", 75))
if randomY == 0 and randomX == 1:
drawer.penup()
drawer.goto(0,40)
drawer.pendown()
drawer.write("O", align="center",font=("Arial", 75))

Sorry this is really long, but I didn't know any other way I could get help on the question without posting all this code
I've tried giving the turtle a name in the printTurtleBoard() function to see if that would solve anything, but the same problem persisted
Solution 1:[1]
you are making letterO a function() and before that, declaring it as a varible. im not sure if this will fix your main problem, but get rid of the global line. also, you are defining functions() inside of your main function() un-indent them or add them before or after your main function.
