What is @property ?

＠property 是 Obj-C 2.0 版開始提供的一種功能，目的是要簡化一個 instance variable 的設定過程。

為什麼需要 @property ?

instance variable (以下簡稱 ivar ) 在 Obj-C 裡預設為 protected ，代表只有這個 class or 它的 subclass 可以 access 值。如果這個 ivar 要給外部使用的話，那就必須必須加上 public 的 method setter/getter。然而，每宣告一個要給外部使用的 ivar 就要宣告一組 setter/getter 太麻煩，因此 Obj-C 加入了 @property 的語法。

舉例來說，原本想讓外部的人使用 weight 要這樣寫：

	import numpy as np
	from sklearn.ensemble import EnsembleSelectionClassifier
	from sklearn import datasets
	from sklearn.tree import DecisionTreeClassifier
	from sklearn.ensemble import AdaBoostClassifier
	from sklearn.linear_model import LogisticRegression
	from sklearn.svm import SVC
	from sklearn import cross_validation
	from sklearn.metrics import accuracy_score
	import sklearn.preprocessing as preprocessing
