如何讓按鈕文本從文本更改爲空名稱並延遲？

Question

我爲GUI使用tkinter庫。基本上我使用for循環創建4個按鈕，每個按鈕都有一個隨機數作爲文本。現在我試圖實現一種方法，它允許按鈕文本顯示爲一個數字，然後在第二秒左右變爲無（此操作完成後，下一個按鈕將執行相同的過程）時卡住了。因此，該方法將允許每個按鈕閃爍它的數字，並移動到下一個（直到所有按鈕閃爍一次他們的數字）。

這是我到目前爲止

from tkinter import * 
from tkinter.messagebox import showinfo 
from random import randint 

def set_colors(a): 
    if a == 0: 
     return "red" 
    elif a == 1: 
     return "green" 
    elif a == 2: 
     return "blue" 
    elif a == 3: 
     return "yellow" 

def set_random(): 
    random_int = 0 
    random_int = randint(0, 100) 
    return random_int 

LARGE_FONT = ("Verdana",20) 
color = 0 

root = Tk() 
frame = Frame(root) 
root.title("Test") 
root.geometry("200x200") 
root.resizable(0, 0) 

Grid.rowconfigure(root, 0, weight=1) 
Grid.columnconfigure(root, 0, weight=1) 
frame.grid(row=0, column=0, sticky=N + S + E + W) 
grid = Frame(frame) 
grid.grid(sticky=N + S + E + W, column=0, row=7, columnspan=2) 
Grid.rowconfigure(frame, 7, weight=1) 
Grid.columnconfigure(frame, 0, weight=1) 



for x in range(2): 
    for y in range(2): 
     rand_no = set_random() 
     btn = rand_no 
     btn = Button(frame, text=btn, bg=set_colors(color) , font=LARGE_FONT) 
     btn.grid(column=x, row=y, sticky=N + S + E + W) 
     color += 1 

for x in range(2): 
    Grid.columnconfigure(frame, x, weight=1) 

for y in range(2): 
    Grid.rowconfigure(frame, y, weight=1) 

root.mainloop() 

的output.So的圖片爲止，我計算過，我需要進口的時間庫，並使用了sleep（）方法來獲得所需的延遲代碼。但我仍然需要：

允許面板使用按鈕加載（沒有任何數字） 然後按鈕開始閃爍數字一個接一個，直到所有按鈕閃爍一次數字。
