Python的__init__和self是作什麼的？ - What __init__ and self do on Python?

問題：

I'm learning the Python programming language and I've came across something I don't fully understand. 我正在學習Python編程語言，遇到了一些我不太瞭解的東西。

In a method like: 用相似的方法：

def method(self, blah):
    def __init__(?):
        ....
    ....

What does self do? self作什麼的？ What is it meant to be? 這是什麼意思？ Is it mandatory? 它是強制性的嗎？

What does the __init__ method do? __init__方法有什麼做用？ Why is it necessary? 爲何有必要？ (etc.) （等等。）

I think they might be OOP constructs, but I don't know very much. 我認爲它們多是OOP構造，但我不太瞭解。
