Python-如何使用不同的方法填充pygame屏幕

我试图在tkinter表单中为使用pygame的程序设置一个重置按钮

重置按钮必须重置pygame屏幕，这意味着填充一种颜色，在我的情况下是黑色

我将不显示完整的代码，因为它很长，而是片段

btn_reset = Button(simFrame)
    btn_reset.config(text = "Reset", borderwidth = 2, padx = 0, pady=0, width = 8)
    btn_reset.bind("<Button-1>", self.reset) #left click to acvtivate
    btn_reset.grid(row = 8, column = 0, sticky = W)

这就是我想做的，显然这不起作用

屏幕已经用另一种方法制作，如何从这个方法填充

或者更好，我可以在激活按钮时从pygame方法中填充屏幕吗
