Pygame window not showing up

I recently downloaded pygame on my Mac, but for some reason, the window does not pop up with the screen or anything. I don't get an error message, it just runs but doesn't actually pop up a display.

import pygame, sys
from pygame.locals import*
pygame.init()
SCREENWIDTH = 800
SCREENHEIGHT = 800
RED = (255,0,0)
screen = pygame.display.set_mode((SCREENWIDTH, SCREENHEIGHT))
pygame.draw.rect(screen, RED, (400, 400, 20, 20),0)
screen.fill(RED)
pygame.display.update()

Your code is currently starting, drawing a red rectangle in a window, and then ending immediatly. You should probably wait for the user to quit before closing the window. Try the following:

import pygame, sys
from pygame.locals import*
pygame.init()
SCREENWIDTH = 800
SCREENHEIGHT = 800
RED = (255,0,0)
screen = pygame.display.set_mode((SCREENWIDTH, SCREENHEIGHT))
pygame.draw.rect(screen, RED, (400, 400, 20, 20),0)
screen.fill(RED)
pygame.display.update()
# waint until user quits
running = True
while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False
pygame.quit()

The loop in the end will ensure that the window remains open until the user closes it.

Please check this solution.

import pygame, sys
from pygame.locals import *
pygame.init()
SCREENWIDTH = 800
SCREENHEIGHT = 800
RED = (255, 0, 0)
screen = pygame.display.set_mode((SCREENWIDTH, SCREENHEIGHT))
while True: pygame.draw.rect(screen, RED, (400, 400, 20, 20), 0) screen.fill(RED) pygame.display.update()

use fill before using draw.rect or bilt

screen.fill(RED)
pygame.draw.rect(screen, RED, (400, 400, 20, 20),0)

Ok, to fix this problem go into any text editor (IDLE will do fine, so will notepad) Type the following code:

YourFileName.py

pause

Then, click on 'file' then click on 'save as' and a screen should pop up asking you to name it. Name it: YourFileName.bat
Save it in a folder that you can easily open

the way that you open the screen with PyGame is simply by double clicking the file I just showed you how to create. Then it will immediately run your code in PyGame.
