I know this title look familiar to some old questions, but i've looked at every single one of them, none of them solves. And here is my codes:

我知道这个题目看起来很熟悉一些老问题，但我已经看过了其中的每一个，没有一个能解决。这是我的代码:

class Island (object):E,W,R,P
  def __init__(self, x, y):
    self.init_animals(y)
  def init_animals(y):
    pass

isle = Island(x,y)

However, i got the following error:

但是，我有以下错误:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in __init__
TypeError: init_animals() takes 1 positional arguments but 2 were given

Please tell me if i got any mistakes, im so confused by this. Best regards

You need to add self as the first argument of init_animals:

你需要把self作为init_animals的第一个参数:

def init_animals(self, y):
    pass

self (similar to this in Java) is the instance of the class. Every time you call a method within the class, self is sent to that method as the first argument.

self(类似于Java中的这个)是类的实例。每次在类中调用方法时，self被发送到该方法作为第一个参数。
