python的turtle pen怎么赋值

1105748041

请问大家怎么把pen speed和pen width赋值给画笔以及实现hide turtle和hide trace（跳过画图过程）功能，图片和代码如下：
from tkinter import *
from tkinter.ttk import *
from turtle import *
import turtlefigures
from tkinter import colorchooser

# create an empty frame and setup its geometry
root = Tk()
root.geometry("800x500+200+200")
root.title("Turtle Interface")

# create the canvas
canvasFrame = LabelFrame(root, text = "Turtle Canvas")
canvas = Canvas(canvasFrame, width = 400, height = 400)
canvas.pack()
canvasFrame.grid(row = 0, column = 4, rowspan = 3, columnspan = 3,
                 padx = 10, pady = 10)

# make the screen
screen = TurtleScreen(canvas)
screen.bgcolor("white")
w, h = screen.screensize()


# make the pen
pen = RawTurtle(screen)
pen.color("red")
pen.width(3)

# make a control panel and grid it
controlFrame = LabelFrame(root, text = "Control Panel")
controlFrame.grid(row = 0, column = 0, columnspan = 3, padx = 10)
        
def getColor():
    color_code = colorchooser.askcolor()
colorButton = Button(controlFrame, text = "Pen Color Picker", command = getColor)
colorButton.grid(row = 0, column = 0, columnspan = 3,pady=10,ipadx=50,ipady=10)

#create speed scale
def penSpeed(currentSpeed):
    currentSpeed = penspeedStr.get()
    pen.speed(currentSpeed)

penspeedStr=DoubleVar()
scale = Scale(controlFrame,orient=HORIZONTAL,length=150,from_=0.0,to=10.0,
              variable=penSpeed,command=penSpeed)
scale.bind('<ButtonRelease-1>',penSpeed)
scale.grid(row = 1, column = 1, columnspan = 3)
penspeedLabel = Label(controlFrame,text='Pen Speed')
penspeedLabel.grid(row = 1, column = 0,pady=10)



#create size scale

    currentSize = pensizeStr.get()
    pen.size(currentSize)
pensizeStr=DoubleVar()
