Turtle window not closing

[Harshika Varadhan]

Thank you for your response. I apologize for that, this is my first time posting so I wasn't sure how to copy my code! 
I figured out that using the clear() method works for clearing the turtle window after drawing the game board, but now I am trying to figure out how to make the program wait a few seconds or wait for the user to press a key before clearing the turtle window (not closing the window, just clearing it). Is there any way to do this?

def draw_board():
    t = turtle.Turtle()
    t.speed(0)
    t.ht()
    t.up()
    t.goto(-100, -100)
    t.down()

    for i in range(7, -1, -1):
        for j in range(0, 8):
            if free_squares[i][j] == ".":
                if j != 7:
                    t.fillcolor("green")
                    t.pencolor("black")
                    t.begin_fill()
                    for k in range(4):
                        t.forward(50)
                        t.left(90)
                    t.end_fill()
                    t.forward(50)
                if j == 7:
                    t.fillcolor("green")
                    t.pencolor("black")
                    t.begin_fill()
                    for k in range(4):
                        t.forward(50)
                        t.left(90)
                    t.end_fill()
                    t.right(270)
                    t.forward(50)
                    t.left(90)
                    t.forward(350)
                    t.right(180)
            else:
                if j != 7:
                    for l in range(4):
                        t.forward(50)
                        t.left(90)
                    t.forward(50)
                if j == 7:
                    for l in range(4):
                        t.forward(50)
                        t.left(90)
                    t.end_fill()
                    t.right(270)
                    t.forward(50)
                    t.left(90)
                    t.forward(350)
                    t.right(180)
    wn.clear()
I appreciate your help.
Thanks,
Harshi

It probably raises an exception and prints a traceback. That "traceback" 

contains the location and a description of the error Python encountered in 

your script and is therefore valuable information that can help you fix your 

code. If you get a traceback always include it into your mail (use cut-and-

paste).

That's pretty unreadable. Please remember to post plain text with line-

wrapping turned off next time.


> the program ends up crashing.


If I were to guess: Did you define the `free_squares` list of lists 

properly?

Are you running your script from within IDLE? Try starting it from the 

command line instead.


Like turtle IDLE itself is a program written in tkinter, and the separation 

between editer and user code is not always perfect.
