在 tkinter label 中顯示時間

Question

我試圖讓當前時間在 tkinter label 中每秒顯示和更新。

我假設我這樣做完全錯誤。 我對此很陌生，並試圖一點一點地解決它。

from tkinter import *
import sys
import time

#function to close window when ESC is pressed
def close(event):
    sys.exit()

def curtime():
    while 1==1:
        current_time = time.strftime('%H:%M:%S')
        print(current_time)
        time.sleep(1)

#Main System
window = Tk()
window.state('zoomed')
window.configure(bg='#3a3a3a')

#Frames
top_frame = Frame(window)
top_frame.pack(side=TOP)
bottom_frame = Frame(window)
bottom_frame.pack(side=BOTTOM)

#Labels
header_label = Label(top_frame, text="SARA", background='#3a3a3a', fg='#ffffff', font=("calibri", 50))
header_label.pack(side=LEFT)



header_label2 = Label(top_frame, textvariable = curtime(), background='#3a3a3a', fg='#ffffff', font=("calibri", 50))
header_label2.pack(side=LEFT)




#on press ESC window closes
window.bind('<Escape>', close)
window.mainloop()

#function to get timer to calculate
def timer():
    timer_tick = strftime("%I:%M:%S")
    time_label.configure(text=timer_tick)
    time_label.after(1000, timer)

time_label = Label(top_frame, background='#3a3a3a', fg='#ffffff', font=("calibri", 50))
time_label.pack(side=LEFT)




#if statement which constantly returns true to make the timer refresh and tick
if __name__ == "__main__":
    timer()
