Can I call a function by clicking ‘OK’ in messagebox.showinfo?

I have added a message box in my code and I want to call a function defined earlier when clicking the ‘OK’ button in the message box. Is there any way to achieve this? Thanks in advance.

messagebox.showinfo('Correct', 'Correct!nClick OK to continue')

Answer

When you make a showinfo box, it actually halts your script until you press OK. All you will need to do is put the function you want right after it.

See this example:

import tkinter as tk
from tkinter import messagebox

def go():
    messagebox.showinfo('Correct', 'Correct!nClick OK to continue')
    print('yeah')

root = tk.Tk()

btn = tk.Button(root, text='click', command=go)
btn.pack()

root.mainloop()

If you run that, you will see the print('yeah') only happens when the user clicks OK. So, you can do something similar and call the function where I have put the print.
