-------------------------------------------------------------------------------- 1 | Black Cookbook in Dwarf Artisan 2 | ============= 3 | 4 | Welcome to Dwarf Artisan's Black Cookbook. 5 | 6 | This this a fork from [Xia Chu Fang Black Cookbook](https://github.com/xiachufang/BlackCookbook), a knowlage code library. 7 | 8 | 下厨房黑科技 9 | =================== 10 | 11 | 下厨房技术团队的开放仓库。这里主要下厨房的工程师们在工作和学习研究过程中积累的 12 | 心得体会。包括一些练习和尝试。 13 | 14 | 不怕笨拙，积极KUSO。为我们自己的成长喝彩。为我们这个不靠谱团队成长为知名不靠谱 15 | 团队做出自己的贡献。 16 | 17 | 在黑科技仓库，我们鼓励过度设计，面条代码，各种非实用技术的尝试。更欢迎大家留下 18 | 翔实的文档，严谨的测试。在工程师独有的娱乐中成长为砖家。 19 | 20 | 关于下厨房 21 | ============= 22 | 23 | 下厨房美食菜谱网倡导在家烹饪、健康的生活方式，提供有版权的实用菜谱与饮食知识，为厨艺爱好者搭建一个真诚、有爱的记录分享平台。 24 | 25 | 下厨房非常年轻，但发展速度惊人。自2011年3月上线以来，以与众不同的简洁设计、方便实用的菜谱信息、文艺有爱的气质情怀，从众多同类型网站中脱颖而出，获得了来自各方的好评，以及忠诚度极高的用户。网站目前已有超过20万注册用户，拥有超过200名美食领袖人物作为认证专家，用户活跃度高达30%，网站PR为4，博客PR为5。这个数字还在持续快速增加。 26 | 27 | 网站数据 28 | ---------------------- 29 | 月均访问IP：150—180万，月均访问PV：750—900万 30 | alexa排名中国1100名左右 31 | 32 | 下厨房以【网站+博客+邮件EDM+移动客户端+社会化平台】的方式，进行多方位运营。网站提供近10万道有情怀有掌故的菜谱信息；博客通过书影音等文章专题传递“唯有美食与爱不可辜负”的价值观；邮件EDM以诗情画意的意境结合实用性受到用户一致好评；安卓与iPhone移动客户端一经推出便得到了多方关注，下载安装量逾百万；在社会化平台方面，下厨房的新浪微博、QQ空间、豆瓣小站、人人小站、点点等，都各自拥有数量庞大的忠诚粉丝，互动性极高。 33 | 34 | 下厨房不妄称自己是最大最好的，用户认可我们为“最文艺最有爱的菜谱网站”，这比任何自夸都更具含金量。真诚，是下厨房最好的口碑。未来，我们期待在美食领域做得更多。 35 | 36 | 关于的关于 37 | =============== 38 | 39 | 一个正在穿着睡衣上班的胖子代表 Black Cookbook 向提供此文案的有爱的下厨房官方表示感谢。

metaclass 10 | ==================== 11 | 调用对象成员时，Python 先查找对象的定义，然后是 metaclass，然后是父类。 12 | 13 | 需要引入来自多个类型的定义，但是又不想使用多继承时，metaclass 是一个可选的方法。 14 | 15 | Python 2 中，可以通过定义类成员 __metaclass__ 引入元类。在 Python 3 中， 16 | 我们使用形如 class X(metaclass=Meta) 的方式。 17 | 18 | type.__new__ 19 | ==================== 20 | 经常在介绍 metaclass 的文章里出现的形如 21 | 22 | :: 23 | class MetaClass(type): 24 | def __new__(meta, name, bases, attr): 25 | ... 26 | type.__new__(meta, name, bases, attr) 27 | 28 | 的示例其实有点误导人，type.__new__ 只是 metaclass 编程中常用到的一个技巧。 29 | 但是它本身跟 metaclass 没什么必然联系。type.__new__ 构造出一个类型而非普通的实例对象， 30 | 这样，只要像函数一样调用这个类型，就会构造出实例对象，这就是我们通常在 Python 31 | 代码中定义对象的形式 32 | 33 | :: 34 | obj = MyClass(param) #type.__new__ 返回的结果就是 MyClass 之类的东西 35 | 36 | 通常 metaclass 编程会用到这个方法，主要是为了通过重载 __new__ 定义，抢在 __init__ 之前 37 | 做一些魔术动作，例如加载一些实例变量，但是如果没有这个需要的话，metaclass 就跟普通的类定义 38 | 没什么区别，只是将 metaclass 与类定义组合起来，合并成为一个类而已。 39 | 40 | 真正的魔法是 type.__new__ ，它可以在运行时动态的构造新的类型。我在 socrates 41 | 项目中使用过这个技巧。 42 | 43 | """ 44 |
