Question

我的标题可能有点混乱，但我基本上想要每四秒画一组不同的形状然后重新开始。例如，第二个我想绘制三角形，第二个我想绘制线条，第二个我想绘制矩形，第二个我想绘制椭圆。第二个五，我希望这个过程重复。我的想法是使用剩下的工作到第二个七。这也可以在不导入任何其他模块的情况下完成。任何帮助都会很棒，如果不清楚，请询问。

谢谢，斯科特

以下是我目前要运行的代码：

from tkinter import *

#creates a class
class mainWindow():
    def __init__(self,theWindow,winName):

        #Sets values for variable
        self.running = 0

        #makes theWindow and instnace var
        self.theWindow = theWindow

        #creates the main frames
        self.mainFrame = Frame(theWindow,width=600,height=200,bg="light gray")
        self.secondframe = Frame(theWindow,width=600, height =287, bg = "green")

        self.mainFrame.grid()
        self.secondframe.grid()

        # gives the window a title
        theWindow.title(winName)

        # do not resize window based on widgets
        self.mainFrame.grid_propagate(False)

        # window location
        theWindow.geometry('+500+300')

        #Makes it so the window wont resize
        self.theWindow.resizable(0,0)

您正在寻找的是如何使用.after方法。

以下是它的工作原理。

Lbl = Label()
Lbl.pack()
Lbl.after([Amount of milliseconds], lamba: [Function])

对于更高级的表示法，

after(delay_ms, callback=None, *args)

这样做是为了注册在给定时间后调用的警报回调

如何每秒发生不同的动作，然后每四秒重复一次
