What are all the special (magic) methods in Python? The __xxx__ methods, that is.

我经常寻找一种方法来覆盖我知道可以通过其中一种方法完成的事情，但是我很难找到方法，因为据我所知没有明确的列表在这些方法中，加上它们的名字并不是真正的 Google 友好的.所以我认为在 SO 上列出这些人的名单是个好主意.

I'm often looking for a way to override something which I know is possible to do through one of these methods, but I'm having a hard time to find how since as far as I can tell there is no definitive list of these methods, PLUS their names are not really Google friendly.

推荐答案

At the python level, most of them are documented in the language reference. At the C level, you can find it under the object protocol section (strictly speaking, you only have a subset here, though).
