如何用python制作这9个不同颜色和大小的球

所以我试着让9个不同的球以不同的颜色、大小和不同的动作出现。到目前为止，我有9个球，但它们有时颜色相同，大小相同，运动轨迹几乎相同。 不知道我该换什么

from tkinter import *
import time
import random

WIDTH = 800
HEIGHT = 500
SIZE = random.randrange(10,100,10)
tk = Tk()
canvas = Canvas(tk, width=WIDTH, height=HEIGHT, bg="grey")
canvas.pack()
colors = ['black', 'blue', 'yellow','orange','green','purple', 'maroon', 'teal', 'brown']
balls = []

for _ in range (10):
    balls.append(canvas.create_oval(0, 0, SIZE, SIZE, fill=random.choice(colors)))

class Ball:
    def __init__(self):
        for self.shape in balls:
            self.speedx = 9 # changed from 3 to 9
            self.speedy = 9 # changed from 3 to 9
            self.active = True
            self.move_active()

    def ball_update(self):
        for self.shape in balls:
            canvas.move(self.shape, self.speedx, self.speedy)
            pos = canvas.coords(self.shape)
            if pos[2] >= WIDTH or pos[0] <= 0:
                self.speedx *= -1
            if pos[3] >= HEIGHT or pos[1] <= 0:
                self.speedy *= -1

    def move_active(self):
        if self.active:
            self.ball_update()
            tk.after(40, self.move_active) # changed from 10ms to 30ms


ball = Ball()
tk.mainloop()

如果您总是从同一个列表中获得随机值，则项目可以重复。有时，你可以随机获得所有物品的相同颜色。最好一个接一个地从列表中获取颜色，而不是随机获取

for color in COLORS:
     ball_id = canvas.create_oval(..., fill=color)

仅在开始时选择一次“大小”，然后使用“大小”中的相同值。您应该为范围为10的uu选择循环内的随机大小

每个球在相同的位置0,0开始，使用相同的speedx，speedx，因此它可以以相同的方式移动。他们应该从不同的地方开始。每个球都应该有自己的速度变量

for color in COLORS:
    size = random.randrange(10, 50, 5)

    x = random.randrange(0, WIDTH, 10)
    y = random.randrange(0, HEIGHT, 10)

    speedx = random.choice([-9, -6, -3, 3, 6, 9]) # skip `0`
    speedy = random.choice([-9, -6, -3, 3, 6, 9]) # skip `0`

    ball_id = canvas.create_oval(x, y, x+size, y+size, fill=color)

    ball = [ball_id, speedx, speedy]

    balls.append(ball)

顺便说一句：职业球应该只保留关于一个球的信息，并且只移动这个球。你们的班级舞会很像应用程序，所以我改了名字

如果您总是从同一个列表中获得随机值，则项目可以重复。有时，你可以随机获得所有物品的相同颜色。也许你不应该随机获得颜色，而应该在颜色中使用颜色：balls.appendcanvas.create_oval。。。fill=color仅选择一次大小，以后使用与“大小”相同的值。你应该在圈内为u10:`选择随机大小：`每个球在相同的位置0,0开始，因此它可以以相同的方式移动。他们应该从不同的地方开始。每个球都应该有自己的速度变量。我建议阅读下面的文章：。因为我将继续使用你的格式，当它位于一个布局中时，学习编码会容易得多，我可以使用它来保持一切井然有序。有一次我把两者并排比较，我真的明白你在说什么。
