Well, what's the matter?

Question

Python

Hello!
I'm learning pygame, and then a strange situation arose when I run the code, a black window comes out, I click on the cross of this window, and only then the real window comes out, what's the matter ??
here is the window:

here is the real window after clicking on the cross of the black window:

here is the code itself:

import pygame
p = pygame
window = p.display.set_mode((400, 400))
p.display.set_caption('Hellow World')
screen = p.Surface((400, 400))

square = p.Surface((40, 40))
square.fill((0, 255, 0))

done = True
while done:
  for e in p.event.get():
    if e.type == p.QUIT:
      done = False
screen.fill((50, 50, 50))
screen.blit(square, (50, 100))
window.blit(screen, (0, 0))
p.display.flip()

Thank you

Answer 1

Shouldn't these lines be at the end?

done = True
while done:
  for e in p.event.get():
    if e.type == p.QUIT:
      done = False

Answer 2

I understand that the first window is something like a console, no?
Try to save the file in the .pyw extension.
If it is the same, then look for the problem in the thematic sections.
