如何讓每秒都有不同的動作發生，然後每四秒重複一次

Question

我的標題可能有些令人困惑，但我基本上希望每四秒鐘繪製一組不同的形狀，然後重新開始。例如，第二個我想繪製三角形，第二個我想繪製線條，第二個我想繪製矩形，第二個四個繪製橢圓。第二個五我希望這個過程重複。我的想法是使用剩下的工作到七點。也可以這樣做，不需要導入任何額外的模塊。任何幫助都很好，如果有什麼不清楚的地方，請問。

感謝， 斯科特

這裏是我當前的代碼，如果你想運行：

from tkinter import * 
from random 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) 

     # 
     self.theWindow.wm_attributes("-topmost",1) 


`enter code here`#Creates the three frames that will be used

你所尋找的是如何使用的。經過方法。

這是它是如何工作的。

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

對於更高級的符號，

after(delay_ms, callback=None, *args) 

這裏做的事情是，它註冊了在給定的時間後調用
