从 init 调用时无法获取属性值
Not able to get attributes value while calling from init
在 __init__ 方法中，当我尝试访问 get_movie_detail 时，它显示 object 没有 attribute.This 的错误，当我尝试从列表中获取数据时发生.当我尝试在 get_movie_detail 中返回单个变量时，例如。 return title，它成功返回了标题，但如果我尝试处理列表，则会出现以下错误：

您不需要尝试访问 detail_list，您的 detail_new 就是那个列表。
您可以通过访问detail_new[0]获得标题。
所以你的 __init__() 函数的那部分变成：
self.title = detail_new[0]
self.imdb_rating = detail_new[1]
self.movie_overview = detail_new[2]
self.release_date = detail_new[3]
