How to uninstall a .exe from a python script

Hello I can't get an app to self uninstall. After converting a .py script to .exe when I press the button it is supposed to delete/uninstall itself from my computer.

Actually I would like it to uninstall completely from my computer after pressing the button from the .exe how to do it?

Here is the code:

from tkinter import * 
import os 



root = Tk()
root.geometry("300x400")



def func(*args): 
    
    os.remove(__file__)
    root.destroy()




Button1 = Button(root,text="Delete",fg="green",width=10,height=5)
Button1.pack(side=TOP)

Button1.bind('<Button-1>', func)

root.mainloop()

I expect the program to self uninstall after I press the button and I tried the code above that doesn't work (when I convert the .py file to a .exe file the exe file is not deleting itself when I press the button on the .exe file)

EDIT: The code above work with python file .py but not with .exe files ! why ?

Solution

After a lot of searching, I found a solution using this answer!

The trick is to start a separate external process that deletes the file after a delay

from tkinter import Tk, Button, TOP
import subprocess
import sys

def func(*args):
    root.destroy()
    subprocess.Popen(f"cmd /c ping localhost -n 3 > nul & del {sys.executable}")

root = Tk()
root.geometry("300x400")

Button1 = Button(root,text="Delete",fg="green",width=10,height=5)
Button1.pack(side=TOP)
Button1.bind('<Button-1>', func)
root.mainloop()

This answer explains why you should use sys.executable instead of __file__ inside the exe

I tried these approaches without success

Registering the removal of the file with atexit
Starting a daemon thread to remove the file after a delay with threading
Starting a daemon process to remove the file after a delay with multiprocessing
Running os.chmod to change permissions
Running as administrator

Tested with pyinstaller --onefile randomtesting.py (pip install pyinstaller)
