Tkinter command function call

Question

I am new with python , And since i started python the command call in Tkinter never works for me I have tried all the ways and i took of the brakets off but it doesn't work still i have seen the related topics here but they didn't work for me here is a simple code that i have tried noting that when i clic the button nothing happens so where is the problem coming from?

from tkinter import *
if __name__ == "__main__":
    
    root = Tk()
    root.geometry("400x400")
    compile_button=Button(root,text="Compiler",command=root.quit)
    compile_button.pack()

It works fine by adding `root.mainloop()` after `compile_button.pack()`. — acw1668, Feb 09 '21 at 15:19

Add root.mainloop() at the end of your __main__. So the GUI starts working. For further info check out this question.
You can also use root.destroy method.

The whole code:

from tkinter import *

if __name__ == "__main__":
    root = Tk()
    root.geometry("400x400")
    compile_button=Button(root,text="Compiler", command=root.quit)
    compile_button.pack()
    root.mainloop()

Mmm. What version of Tkinter are you using? Are you executing the python file from command line or in some IDE? Are you sure you copied the code correctly? – Jakub Szlaur Feb 09 '21 at 08:13
