This is a tutorial on XML processing with lxml.etree . It briefly overviews the main concepts of the ElementTree API , and some simple enhancements that make your life as a programmer easier. If your code only uses the ElementTree API and does not rely on any functionality that is specific to lxml.etree , you can also use (any part of) the following import chain as a fall-back to the original ElementTree:
With the continued growth of both Python and XML, there is a plethora of packages out there that help you read, generate, and modify XML files from Python scripts.

A dictionary is mutable and is another container type that can store any number of Python objects, including other container types. Dictionaries consist of pairs (called items) of keys and their corresponding values. Python dictionaries are also known as associative arrays or hash tables.
Introduction Threads allow applications to perform multiple tasks at once. Multi-threading is important in many applications, from primitive servers to today's complex and hardware-demanding games, so, naturally, many programming languages sport the ability to deal with threads.
Twisted framework is an event based networking framework in Python.
Do you want to crack MD5 hashes in at a rate of ~300MHash/s without a massive rainbow table? Do you have a CUDA enabled GFX card?
I have always had a keen interest in cryptography and rather than give a brief history of cryptography I will recommend reading Simon Singh’s The code book or for a modern and hands on approach Applied Cryptography by Bruce Schneier (Who also made a brilliant book on security, more of descriptive approach but very interesting Secrets and Lies: Digital Security in a Networked World ).
