Question

所以我是Python新手，必须做一个项目，我们使用tkinter GUI创建一个生成龟图的界面。我们20％的分数用于个人对界面的贡献，因此我希望能够通过从选项菜单中选择来改变乌龟笔的颜色，例如：当＆＃39;二叉树＆＃39;如果选中，您可以选择红色，它将以红色而不是默认黑色绘制。到目前为止，我花了8个小时的骨头试图让它发挥作用。有人可以帮助我或告诉我它是否可以做到？到目前为止，这是我的代码：

# Import the Modules
from turtle import *
from tkinter import *
from tkinter.ttk import Entry, OptionMenu

library = ["Binary Tree", "Dandelion", "Fern", "Flake", "Square Gasket", "Swiss Flag", "Square Gasket", "Circle Gasket"]
colorLibrary = ["black", "red", "blue", "green", "cyan", "magenta", "white", "yellow"]


#Create an empty window and give it's width and height
 root = Tk()
 root.title("Turtle Fractals")
 root.geometry("400x200+300+300")

#Set the pen speed & width
 pen = Pen()
 pen.speed(0)
 pen.width(1)

 screen.bgcolor("grey")

 # get the string and make it an integer

 length = int(lengthStr.get())

为我的代码状态道歉。一旦我完成这项工作，我就会清理它并发表更多评论。提前谢谢。
