Turtle 窗口
請看下圖，turtle窗口圖標是一片小葉子，估計它就是繼承自 tkinter 庫。
tkinter 窗口
參閱了一些資料，發現 turtle 方法可直接在 tkinter 的畫布Canvas上操作：
源代碼
from tkinter import *
from turtle import RawTurtle
def circ():
tu.penup()
tu.home()
tu.clear()
tu.speed(0)
[x,y,R] = et1.get().split(",")
try:
x = int(x.replace("(",""))
y = int(y.replace(")",""))
R = int(R.strip())
except:
x,y,R = 0,0,50 #輸入錯誤則賦予默認值
tu.goto(x,y-R)
tu.pendown()
tu.circle(R)
def rect():
tu.penup()
tu.home()
tu.clear()
tu.speed(0)
tu.color("red", "yellow")
tu.begin_fill()
[d,rad] = et2.get().split(",")
try:
d = int(d)
rad = int(rad)
except:
d,rad = 200,216 #輸入錯誤則賦予默認值
tu.pendown()
tu.back(d//5)
while True:
tu.forward(d)
tu.left(rad)
if abs(tu.pos()[0]+d//5)<0.1 and abs(tu.pos()[1])<0.1:
break
tu.end_fill()
def taiji():
tu.penup()
tu.home()
tu.clear()
tu.speed(0)
d = et3.get()
try:
d = int(d)
except:
d = 120 #輸入錯誤則賦予默認值
tu.hideturtle()
tu.goto(d//2,-d)
tu.pendown()
tu.begin_fill()
tu.color("black","black")
tu.circle(d,extent=180)
tu.circle(d//2,extent=180)
tu.circle(-d//2,extent=180)
tu.end_fill()
tu.circle(-d,extent=180)
tu.penup()
tu.goto(d//2,-d//6*4)
tu.pendown()
tu.begin_fill()
tu.fillcolor("black")
tu.circle(d//5,extent=360)
tu.end_fill()
tu.penup()
tu.goto(d//2,d//3)
tu.pendown()
tu.begin_fill()
tu.fillcolor("white")
tu.circle(d//5,extent=360)
tu.end_fill()
tu.penup()
def main():
global tu,et1,et2,et3
root = Tk()
root.geometry("520x520+150+300")
root.title("turtle在tkinter.Canvas上的操作")
root.resizable(False, False)
canvas = Canvas(root, width=640, height=400)
canvas.pack()
tu = RawTurtle(canvas)
tu.hideturtle()
et1 = Entry(root, width=12)
et1.place(x = 30, y = 480)
et1.insert(0,"(50,-20), 100")
bt1 = Button(root,text=" 畫圓 ",command=circ)
bt1.place(x = 60, y = 425)
et2 = Entry(root, width=12)
et2.place(x = 190, y = 480)
et2.insert(0,"200, 216")
bt2 = Button(root,text=" 多角星(或多邊形) ",command=rect)
bt2.place(x = 180, y = 425)
et3 = Entry(root, width=12)
et3.place(x = 360, y = 480)
et3.insert(0,"120")
bt3 = Button(root,text=" 太極 ",command=taiji)
bt3.place(x = 380, y = 425)
root.mainloop()
if __name__ == "__main__":
main()
turtle和tkinter混合使用
turtle和tkinter兩者搭配使用，使得 turtle 的畫圖參數可以由 tkinter 的控件當場設置，這樣就實現了turtle小海龜的現場互動，運行效果見圖二。
三個Entry控件，分別設置：
1. 圓心坐標和圓的直徑；
2. 多邊形的邊長和邊的轉動角度；
3. 太極圖的外圓直徑。
