Python Snake游戏索引器:列表索引超出范围
我的snake代码有问题,并且不断收到indexer:list索引超出范围的错误消息 我想问题出在114行Python Snake游戏索引器:列表索引超出范围,python,pygame,Python,Pygame,我的snake代码有问题,并且不断收到indexer:list索引超出范围的错误消息 我想问题出在114行 for choice in selection: pygame.draw.rect(screen,WHITE,choice,0) # redraw selected button in another colour pygame.draw.rect(screen,GREEN,sele
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)
如果代码中有任何其他问题,如bug或不一致,请告诉我
但是如果您找到了索引问题的解决方案,请解释一下,因为我是python新手
此外,一个解决方案也会有所帮助
