I'm trying to make some GUI on Python3 with tkinter. So far I have Main Window and 'Test' button on it, which opens second window. Second window has entry, label, save and close buttons. When you type something in entry and press save button, label shows the text you typed in entry. But after closing this window and opening it again, label shows nothing. How do I make this label to show the text that were typed last time before closing? For example, I type 'Hi' in entry, press 'Save', then I press 'Close', then I open this window again and label shows 'Hi'

import tkinter as tk

def save_data(entry, t):
 t.config(text = entry.get())

def close_action(current_window):
 current_window.destroy()

def insertMainInfo():
 new_window = tk.Tk()
 new_window.geometry("307x131")
 new_window.title("TestWindow")

 test_entry = tk.Entry(new_window)
 test_entry.place(relx = 0.283, rely = 0.1, height = 24, width = 127)

 text = tk.Label(new_window)
 text.place(relx = 0.283, rely = 0.25, height = 24, width = 127)

 save_button = tk.Button(new_window, command = lambda: save_data(test_entry, text))
 save_button.place(relx=0.283, rely=0.45, height=24, width=127)
 save_button.configure(text = "Save")

 close = tk.Button(new_window, command = lambda: close_action(new_window))
 close.place(relx=0.283, rely=0.687, height=24, width=127)
 close.configure(text = "Close")

 new_window.mainloop()

if __name__ == '__main__':

 top = tk.Tk()
 top.geometry("307x131+557+330")
 top.resizable(width=False, height=False)
 top.title("MainWindow")

 new_window_button = tk.Button(top, command = insertMainInfo)
 new_window_button.place(relx=0.283, rely=0.687, height=24, width=127)
 new_window_button.configure(text = "Test")

 main_label = tk.Label(top)
 main_label.place(relx=0.033, rely=0.153, height=41, width=284)
 main_label.configure(text = "TestLabel")

 top.mainloop()
