New-style Classes

Unfortunately(遗憾，不幸的), new-style classes have not yet been integrated(集成) into Python's standard documention. Fear(担心) not, however; many people have worked to provide useful information on creating and using new-style classes:

• Unifying types and classes (aka descrintro) is Guido's essay(文章) on new-style classes and should be your starting point(起点).
• Raymond Hettinger's How-To Guide for Descriptors focuses on the single most useful aspect(方面) of new-style classes (which includes properties(属性)).
• Python 2.3 Method Resolution Order (MRO) covers(涵盖了) multiple inheritance(继承).
• Metaclasses will make your head explode(头大). Here are several(几个) approaches(方法) to discussing them:
  • David Mertz and Michele Simionato's DeveloperWorks article
  • Mike Fletcher's slideshow
  • Metaclasses in Five Minutes
• Types and Objects is the start of a new-style class tutorial with lots of figures(数据) and examples, but it's rough(粗略的) and not complete(不完整的).
