從tkinter無法控制海龜

Question

我想製作可以從tkinter控制的海龜圖形。除了一件事以外，一切正常：enter code here每當我在條目窗口小部件中鍵入數字並單擊按鈕時，它都不起作用（不繪製）。

請幫助我，如果你可以。如果你想給函數傳遞給回調（不是它的返回值），你應該使用

import turtle 
from tkinter import* 
from random import* 

def colorred(): 
    turtle.color("red") 

def colorblue(): 
    turtle.color("blue") 

def colororange(): 
    turtle.color("orange") 

def coloryellow(): 
    turtle.color("yellow") 

def turtleshape(): 
    shapes=["arrow",'turtle', 'circle', 'square', 'triangle', 'classic'] 
    i=randint(0,5) 
    turtle.shape(shapes[int(i)]) 


'''arrow', 'turtle', 'circle', 'square', 'triangle', 'classic'.'''

Answer 1

：

mysquare=Button(frame,text="square",bg="white",fg="black",width=6,bd=4,command=square) 

也沒有必要將參數傳遞給

這裏的代碼回調函數，你可以使用：

distance=int(disp1.get()) 

因此，代碼應該是這樣的：

import turtle 
from tkinter import * 
from random import * 


def colorred(): 
    turtle.color("red") 


def colorblue(): 
    turtle.color("blue") 


def colororange(): 
    turtle.color("orange") 


def coloryellow(): 
    turtle.color("yellow") 


def turtleshape(): 
    shapes = ["arrow", 'turtle', 'circle', 'square', 'triangle', 'classic'] 
    i = randint(0, 5) 
    turtle.shape(shapes[int(i)]) 


'''arrow', 'turtle', 'circle', 'square', 'triangle', 'classic'.''' 

root = Tk() 
root.title("palindrome checker") 
frame = Frame(root) 
frame.pack() 
ekr = turtle.Screen() 
turtle.tiltangle(90) 
inp1 = IntVar() 
inp2 = IntVar() 
inp3 = IntVar() 
leng1 = inp1.get() 
leng = inp2.get() 
rad = inp3.get() 


def square(): 
    print("clicked") 
    distance = int(disp1.get()) 
    turtle.forward(distance) 
    turtle.left(90) 
    turtle.forward(distance) 
    turtle.left(90) 
    turtle.forward(distance) 
    turtle.left(90) 
    turtle.forward(distance) 
    turtle.left(90) 
    turtle.left(5)

    length = int(disp2.get()) 
    turtle.forward(length)

    turtle.left(5) 


def circle(): 
    radius = int(disp3.get()) 
    turtle.circle(radius) 
    turtle.left(5)
