Question

我试图从我的程序中删除列表堆栈和队列中橙色的所有对象，目前在如何从我的代码进展方面遇到困难，只需要了解如何启动它恰当。我尝试了一下，但似乎只是在创造更多的形状。任何帮助都会非常感谢！

from tkinter import *
import random
root = Tk()
from Stack import Stack
from my_queue import *

class Recta:

  def __init__(self, height=60, width=80 ,colours= []):
    self.height = height
    self.width = width
    self.canvas = Canvas(root)
    self.canvas.pack()
    self.colours = ["red", "orange"]
    self.rects = []
    self.stack = Stack()
    self.queue = Queue()


  def randomCircle(self):
    w = random.randrange(300)
    h = random.randrange(200)
    self.stack.push(self.canvas.create_oval(0,0,w,h,fill= random.choice(self.colours)))


  def randomRects(self):
    w = random.randrange(300)
    h = random.randrange(200)
    self.rects.append(self.canvas.create_rectangle(0, 0, w, h, fill= random.choice(self.colours)))

   def random_arc(self):
    x1 = random.randrange(300)
    y1 = random.randrange(200)
    x2 = random.randrange(300)
    y2 = random.randrange(200)
    e = random.randrange(90) 
    s = 45 + ( 90 -e)/2
    self.queue.enqueue(self.canvas.create_arc( x1, y1, x2, y2 ,start=s,extent=e,fill= random.choice(self.colours)))

 def remove_all_orange_shapes(self):
    if self.randomRects() == "orange":
        self.canvas.delete(self.rects.pop())
    elif self.randomCircle() == "orange":
        self.canvas.delete(self.stack.pop())
    elif self.random_arc() == "orange":
        self.canvas.delete(self.queue.dequeue())




tes = Recta()
tes= Stack()
tes = Queue()
root.mainloop()

使用列表和其他数据结构删除对象
