晚餐时从`客观'入门
原标题:Deriving class from `object` in python

因此,我只读书(我知道其他多种语言),我很混淆一些东西。 我认为,这是因为缺少文件(至少我可以找到文件)。 我在几个网站上读到,你应当从<条码>中选取以下课程:


class Base(object):
    pass

但我看不出什么情况、为什么或何时应该这样做。 是否有这方面的正式文件,我已错过? 这是否具有3.x特征?

最佳回答

不管你是否继承物体,这当然是没有道理的,但是,如果你在你忘掉你决定不向谁去的时候,你就没有 waiting。

如果你最终不从物体继承,一些微妙的物品就得当:

  1. Using properties in classic classes only partly works: get works alright, but set does weird things.
  2. Multiple inheritance behaves differently in classic classes than in classes derived from object.
  3. Also multiple inheritance won t work if you try to mix classic classes with those that subclass object. Whatever you do you want to be consistent.

一些人继续使用传统课程,但需要新行为者除外,其他人则说,他们总是使用新的风格,避免后来徒步开枪。 如果你重新开展单一个人项目,对你来说是好的;如果其共同项目与其他开发商一致的话。

问题回答

在Zahur3类中,无论你是否这样说,都暗含了反对。
