Chapter 1

You can think of the data model as a description of Python as a framework.
While coding with any framework, you spend a lot of time implementing methods that are called by the framework. The same happens when you leverage the Python data model.
写Python代码，就是在写被Python这个框架调用的方法。如果你写的对象足够Pythonic，那么它就能很好的融入Python这个框架，多快好省。理解Python data model是通往Pythonic的必经之路。
