Easily incorporate strong AES encryption into your programs.
“Believe in your infinite potential. Your only limitations are those you set upon yourself.” ― Roy T. Bennett, The Light in the Heart
Pycrypto is a python module that provides cryptographic services. Pycrypto is somewhat similar to JCE (Java Cryptography Extension) for Java. In our experience JCE is more extensive and complete, and the documentation for JCE is also more complete. That being said, pycrypto is a pretty good module covering many aspects of cryptography.

Make your life easier with these itertools when dealing with iterables
“A lie gets halfway around the world before the truth has a chance to get its pants on.” ― Anonymous
Python provides the itertools package which provides convenience functions for many common iterator operations. We have covered count(), cycle() and chain() in the first part of this series, and compress(), dropwhile(), and groupby() in the second part. In this article, we present a few examples of ifilter(), islice(), imap() and izip().
