我正在为udacity做一个代码项目，并且我得到了这两个错误，我没有得到图片。一个错误是括号中的错误，当我删除括号时，我会在代码上出现错误的语法。

您的init方法具有单个下划线。它需要在" init"之前和之后具有双重下指数。
def __init__(self, movie_title, movie_storyline, poster_image, trailer_youtube):
另外，创建Movie_300对象时，您会缺少逗号。它应该看起来像这样（Wikimedia链接后有一个逗号）：
Movie_300 = Movie("300",
"300 spartans vs an amry of persians",
"https://upload.wikimedia.org/wikipedia/en/5/5c/300poster.jpg",
"https://www.youtube.com/watch?v=wDiUG52ZyHQ")
顺便说一句，命名变量的约定是使用所有小写。
