Проблема отображения изображения в игре на Python
Пишу игру на Python. Писать на данном языке программирования начал относительно недавно, поэтому не особо разбираюсь во всех мелочах. Просьба особо не критиковать. Проверил код пару раз. Ошибок в коде не выявил. При запуске кода открывает окно с черным экраном.

Метод screen.fill должен вызываться каждый кадр перед обновлением экрана.
Измените конец главного цикла while:
while not done:
...
screen.fill(RED)
pygame.display.update()
clock.tick(60) # количество кадров
