Is there a way to remove the background window that pops up when calling askopenfilename()?

Question

When I call the basic command:

from tkinter.filedialog import askopenfilename

filename = askopenfilename()

A little window pops up behind the selector screen.

Is there a way to remove this?

Answer 1

It pops up because you need at least a "root" window for each tkinter application. In your case, you aren't creating any root window explicitly, so askopenfilename creates it automatically for you. One solution would be to create the root window explicitly and then hide it, something as follows

from tkinter.filedialog import askopenfilename
from tkinter import Tk

Tk().withdraw()
filename = askopenfilename()
