Question

我是python的新手，目前正尝试使用tkinker制作一个倒数计时器GUI，并且将来会与Arduino集成，以下是我的代码的一部分，它以分钟和秒为输入，并试图显示窗内还剩下多少时间

import tkinter as tk
import serial, time 
from time import sleep
import sys, os

window = tk.Tk()
window.title('Stimulation App')
window.geometry('800x600')
window.configure(background='white')

header_label = tk.Label(window, text='start')
header_label.pack()


minutes_frame = tk.Frame(window)
minutes_frame.pack(side=tk.TOP)
minutes_label = tk.Label(minutes_frame, text='minutes')
minutes_label.pack(side=tk.LEFT)
minute_entry = tk.Entry(minutes_frame)
minute_entry.pack(side=tk.LEFT)

seconds_frame = tk.Frame(window)
seconds_frame.pack(side=tk.TOP)
seconds_label = tk.Label(seconds_frame, text='seconds')
seconds_label.pack(side=tk.LEFT)
second_entry = tk.Entry(seconds_frame)
second_entry.pack(side=tk.LEFT)

result_label = tk.Label(window)
result_label.pack()

try:
    def countdown(i,j):
        i=int(minute_entry.get())
        j=int(second_entry.get())
        k=0
        while True:
            if(j==-1):
                j=59
                i -=1
            if(j > 9):  
                print(str(k)+str(i)+":"+str(j), end="\r")
            else:
                print(str(k)+str(i)+":"+str(k)+str(j), end="\r")
            time.sleep(1)
            j -= 1
            if(i==0 and j==-1):
                break
        if(i==0 and j==-1):
            time.sleep(1)
    countdown(int(minute_entry.get()),int(second_entry.get())) #countdown(min,sec) 

except KeyboardInterrupt:
    ser.close()
    print('\n interrupted')

calculate_btn = tk.Button(window, text='start', command=countdown)
calculate_btn.pack()

window.mainloop()

但是以某种方式我无法将输入信息输入倒数，我的代码出了什么问题？
