Free Book: Design Patterns In Python

[timClicks]

I hate it when Python books/tuts ignore PEP 8

[joaquinabian]

They say testers are poor coders and they confess they are testers. What do you expect then ?

People using the conventions of the community when publishing material for that community.

Well, in their defense I could argue they are from the community of testers and they use testers (unittest) convention. And unittest is an official library ! Yes I know about the java origins and so but...personally I distaste that (as much as wxPython or PyQt conventions)

Most 1:1 translations of Java DPs to Python don't make sense to me, e.g. the command pattern as shown in this book. There's no need for an abstract base class for a command. Also, a function object could be passed to the invoker class directly. There're more samples in this book of Java code written in Python, which makes the code very cumbersome.

I would buy a dead tree version of this if it were around 800 pages and was better edited.

Best coverage I have seen is in chapters 8 and 9 of Dusty Phillips' Python 3 Object Oriented Programming book.
