pygame doesn't show up

Question

I have recently installed PyGame in Python, but something strange happens. When I import it and use it in the terminal, it works fine, but when I try to use it in idle it doesn't work at all. Does someone know why does this happens?

import pygame

pygame.init()

win = pygame.display.set_mode((500, 500))

Exits with the error:

>Traceback (most recent call last):
