TypeError running tic tac toe game

问题

I have a complete tic/tac/toe game. But there is literally one stupid issue. I have no idea what this error IS or how I am getting it. It says my "clicked" function is missing one parameter when called.

Here is my code:

import turtle
import time
import random 

pieces = ["_", "_", "_", "_", "_", "_", "_", "_", "_"]
turn = "X"
def drawgame(brd):
    # draw board
    turtle.setup(600, 600)
    turtle.bgcolor("silver")
    turtle.color("white")
    turtle.width(10)
    turtle.up()

    # Horizontal bars
    turtle.goto(-300, 100)
    turtle.down()
    turtle.forward(600)
    turtle.up()
    turtle.goto(-300, -100)
    turtle.down()
    turtle.forward(600)
    turtle.up()

    # Vertical bars
    turtle.goto(-100, 300)
    turtle.setheading(-90)
    turtle.down()
    turtle.forward(600)
    turtle.up()
    turtle.goto(100, 300)
    turtle.down()
    turtle.forward(600)
    turtle.up()
    turtle.color("blue")
    x, y = -300, 300
    for pos in pieces:
        if pos == "X":
            # Draw X
            turtle.up()
            turtle.goto(x + 20, y - 20)
            turtle.setheading(-45)
            turtle.down()
            turtle.forward(226)
            turtle.up()
            turtle.goto(x + 180, y - 20)
            turtle.setheading(-135)
            turtle.down()
            turtle.forward(226)
            turtle.up()

        elif pos == "O":
            #Draw O
            turtle.up()
            turtle.goto(x + 100, y - 180)
            turtle.setheading(0)
            turtle.down()
            turtle.circle(80)
            turtle.up()
        x += 200
        if x > 100:
            x = -300
            y -= 200

Exception in Tkinter callback Traceback (most recent call last): File "C:\Users\SonicFlash\AppData\Local\Programs\Python\Python37-32\lib\tkinter__init__.py", line 1705, in call return self.func(*args) File "C:\Users\SonicFlash\AppData\Local\Programs\Python\Python37-32\lib\turtle.py", line 675, in eventfun fun(x, y) TypeError: clicked() missing 1 required positional argument: 'y'

回答1:

turtle.onscreenclick(clicked) Calls the callback with two args, x, y, so you need to change that line to:

turtle.onscreenclick(lambda x, y : clicked(board, x, y))

Without using lambda

turtle.onscreenclick(onscreenclick)
def onscreenclick(x, y):
    // Not using board here, so None should be fine
    clicked(None, x, y)
