推荐答案

似乎__init__方法可能未正确覆盖.在单词init之前和之后需要两个下划线，而不仅仅是一个.

另外，从缩进来看，看起来好像是使用自己的__init__方法从创建实例的，还是您跳过了某些地方的代码?

如果可能，请更清楚.

It looks like the __init__ method may not be overridden properly. You need two underscores before and after the word init, not just one.

Also, from the indentation, it looks like the instance is being created from with it''s own __init__ method, or have you skipped some code somewhere?

More clarity, if possible please.
