У меня проблемы с моим змеиным кодом, и я постоянно получаю сообщение об ошибке IndexError: list index of range
Я думаю, что проблема в строке 114
for choice in selection:
pygame.draw.rect(screen,WHITE,choice,0)
# redraw selected button in another colour
pygame.draw.rect(screen,GREEN,selection[num], 0)
Если есть какие-либо другие проблемы в коде, такие как ошибки или несоответствия, пожалуйста, сообщите мне
Но если вы найдете решение проблемы индекса, пожалуйста, объясните это, потому что я новичок в python Также решение будет полезно
