无法将图像加载到游戏中

Question

在这里输入图像描述我正在从一本叫做“电脑编码python For Kids”的书里学到巨蟒--这是一本书，https://www.amazon.com/Computer-Coding-Python-Games-Kids/dp/0241317797--基本上就是你试着点击红色雪花的地方，然后才能找到它。我的问题是，即使我把图像和代码一起存储在同一个文件中，它似乎也找不到图像。如果我尝试编写(C：\Users\Nigel\Desktop\python\查找红色雪花\image\红雪)，则会得到Unicode错误。这是我的密码

这是错误信息

如果您得到了该路径的unicode错误，这意味着您可能没有正确地键入它--您在路径中看到的那些反斜杠通常用于“转义字符”，当您试图键入文件路径时，它们可能会产生干扰。如果您还没有按以下方式键入路径，请尝试以下解决方案之一：

r"C:\Users\Nigel\Desktop\python-games\find the red snowflake\image\red-snow"         # type r before the opening quote to make it a raw-string, which ignores escape characters
"C:\\Users\\Nigel\\Desktop\\python-games\\find the red snowflake\\image\\red-snow"   # use double-slashes to escape being an escape character

另外，请确保在路径中为图像添加文件扩展名。
