Design Patterns in Python
While searching for an algorithm to sort a graph topologically, I found an online version of the book Data Structures and Algorithms with Object-Oriented Design Patterns in Python. This should be mandatory reading for anyone wishing to do something a little bit more complicated in python. (By the way, the website has implementations in Java, C++ and C# as well.)
The author was nice enough to include a link to a fully working python package, in which the classes from the book have been completed and extended to a very nice and easy to use library. Unfortunately it’s unusable in any project, because it has no license. There’s a copyright notice in the package, and a little notice about the copyright on the texts on his website, but no license.
I have mailed the author, asking for an explanation. Let’s see if he answers, and what he has to say…
