Simple Python HTTP server using sockets
I brewed a simple Python-based http server using sockets today and I wanted to share the code, along with some comments. Sure, there is the http.server class, but why not have some fun? 
Building a fully-fledged HTTP server is a big undertaking. I focused on building a small server, supporting only the basic functionality of the Hyper Text Transfer Protocol (namely the GET and HEAD request methods).
Python’s built-in container data types: categorisation and iteration
The aim of this short article is to take a look on the built-in container data types in Python 3.1. This introduction, however, is not a typical one. Typical Python data types tutorials focus on describing individual data types one by one. Here, instead, I try to describe the ways Python container data types can be grouped according to their properties. I also explain when and why some containers are iterable, why others are not. Therefore, the article explains such concepts as:
- mutable and immutable objects,
- hashable objects,
- ordered and unordered objects,
- the relationship between sequence/set/mapping types with the iterable type, and demystifies the implicit sequence iterator in custom sequence containers.
The article assumes the reader has a fundamental understanding of container types in Python.
