  Pygame runs without any issues, but nothing is drawn on the screen
  
  I've been trying to get Pygame to work for a while now. It runs without any issues, but nothing is shown on the screen. 
  I did try to run the Pygame alien example game, it does not show up either - even though music starts playing
  import pygame
  
  pygame.init()
  
  display_width = 800
  display_height = 600
  
  white = (0, 0, 0)
  
  gameDisplay = pygame.display.set_mode((display_width, display_height))
  
  pygame.display.set_caption("This is a game!")
  
  clock = pygame.time.Clock()
  
  running = True
  
  while running is True:
      for event in pygame.event.get():
          if event.type is pygame.QUIT:
              running = False
  
      gameDisplay.fill(white)
  
      pygame.display.update()
      clock.tick(60)
  
  In the above code I tried filling the screen with the color white, but the window is just blank (the default Mac OS colour) 
  EDIT:
  It seems like it is a problem with Mac OS Mojave
  To clarify the code, I tried with red as well as black and white in the end, and nothing shows up
  
  A:
  
  According to this issue at GitHub this is a bug of Python installed with Hombrew.
  
  UPDATE FIX: if you download the official macOS x64 installer package of Python 3.7.2 from the official python page and then pip3 install pygame it works.
