import tkinter,time,random

# 创建颜色列表
COLOR = ['#f173ac','#73b9a2','#fdb933','#d71345','#fffef9','#afdfe4','#ffe600']

# 创建窗口
tk = tkinter.Tk()  # 声明一个TK，初始化一个“窗口”（画一个窗口）
tk.title('弹球游戏')  # 窗口名称
tk.resizable(width=False,height=False)  # 窗口是否可变（长、宽）,也可用0,1表示
tk.wm_attributes('-topmost',1)  # 窗口永远在前

# 创建画布
canvas = tkinter.Canvas(tk,width=600,height=500,bd=0)  # 创建一个“画布”
canvas.pack()  # 将画布添加到窗口中
tk.update()


# 创建背景
