There are many good online environment like eg Codespaces, Replit, Colab
The problem with Pygame is that in need native OS stuff,so no window will show up in browser in these environments.

I don't have Chromebook so untested.

# test_pygame.py
import pygame
pygame.init()

# Set up display
window = pygame.display.set_mode((400, 300))

# Main loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

pygame.quit()
