Hello
I am learning Python for in the pass ten months, and have brought a few
books about Python. Most of them are good books by its only right, and all
of them only teach you how to write Python programs using Python syntax and
Python ways, but no one single Python book explicitly teaches you on how to
analyst your application, and structure your programmes in a way, so that,
it is easy to maintain, easily to reuse, (i.e. use loosely couple), and
easily to extend or add new features (programming to Interface instead of
Implementation) without introduce bugs into your existing working codes.
I recently brought a book called "Head First Design Patterns" published by
O'reilly. This book is simply a gem. It shows you how to use and apply
Design Patterns to analyst and structure your code, so that, the programs
can be easy maintains, reuse, modify and extend. (It is the books I have
been looking for a long time while I am learning Python, but cannot find
one). The only caveat about this book is that the authors use Java (not
Python) in the examples.
I wonder, can any Python guru out there translate the Java examples in the
book into Python examples, or write a similar book in Python, perhaps
called "Head First Design Patterns in Python". I think, this will be a
great addition to Python books, and a great benefit to Python community.
P.S. I am not sure is this the right news group to post this request. 4 2868

I've also wished for a design patterns book aimed at Python, or at least
dynamic languages with first class functions and modules. There's a paper
Python book with "Patterns" in the title, but it has precious little content
in it related to design patterns, at least not the GOF variety.
This web book has the word "Patterns" in it, too: http://www.brpreiss.com/books/opus7/
But looks like it's mainly data structures.
If you do a google search, and also search the Python Cookbook http://aspn.activestate.com/ASPN/Python/Cookbook/
you can find examples of:
Singleton
Borg
Null
Factory
Observer (including a Publish/Subscribe recipe)
Memento
State
Decorator
Masquerading and Adaptation patterns (Alex Martelli paper)
Template (another Alex Martelli paper)
Chain of Responsibility
Proxy
Prototype
There must be good examples in actual source code out there, too.
called "Head First Design Patterns in Python". I think, this will be a great addition to Python books, and a great benefit to Python community.
I just bought this book as well. I must have adult ADD, because I do enjoy
the Head First format, though I disdained it at first.
P.S. I am not sure is this the right news group to post this request.
Yup, this is the place.

Since Python does so many things different, especially compared to
compiled and statically typed languages, do most of the basic design
patterns still apply when writing Python code? If I were to read a
design pattern book (such as Head First Design Patterns), could I apply
their Java examples to Python easily enough, or does Python require a
different perspective when applying patterns?

Hello
Most authors talk about Java/C++, and describe patterns used as a
workaround to their static class model; the dynamic nature of Python
allows for trivial implementations in some cases.
I've seen some design patterns examples on the ActiveState site, and
some discussions some time ago on this list.
But does anyone know of a complete discussion/analysis of patterns in
Python? Books, articles, web pages...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
