以前寫的系列文章，主要的基礎都有了。缺一些的原因是，看的人的基礎太高，所以有些一開始設想太基本的就跳過了。

Transforming Code into Beautiful, Idiomatic Python

Notes from Raymond Hettinger's talk at pycon US 2013 video, slides.

The code examples and direct quotes are all from Raymond's talk. I've reproduced them here for my own edification and the hopes that others will find them as handy as I have!

Python Socket 编程详细介绍

Python 提供了两个基本的 socket 模块：

Socket 它提供了标准的BSD Socket API。
SocketServer 它提供了服务器重心，可以简化网络服务器的开发。

下面讲解下 Socket模块功能。

	#include <Python.h> // Must be first
	#include <vector>
	#include <stdexcept>
	#include "PyUtils.h"
	using namespace std;

	// =====
	// LISTS

	# A naive Python implementation of a function that returns the (first) index of
	# a sequence in a supersequence is the following:

	def subsequence(needle, haystack):
	"""
	Naive subsequence indexer; None if not found
