Feb 13, 2009 · Python has it's own design idioms. Some of the standard patterns apply, others don't. Something like strategy or factories have in-language support that make them transparent. For instance, with first-class types anything can be a factory. There's no need for a factory type, you can use the class directly to construct any object you want.

Mar 3, 2009 · I am looking for any resources that gives examples of Best Practices, Design patterns and the SOLID principles using Python.

What design patterns do common GUI frameworks like Qt, wx, GTK exhibit? I have a feeling like its a mixture of patterns for different components, such as the event loop vs signal/slots or binding vs Key-value observing, and so on.

May 4, 2024 · Design patterns are sometimes described as ways to work around the limitations of your language, and Python simply lacks the limitations that makes the common description of the factory pattern necessary.

Dec 3, 2020 · This question concerns design patterns in Python and is addressed to the software designers. I have several classes inherited from the same abstract class (all they have a similar interface, but the member functions have very different implementations). I want to make a class (or something else) that combines (wraps) all of them.

As of 2021, the accepted answer could be improved in multiple ways because Python has evolved (3.9.x). The same applies to its uncredited original source. First of all, the implementation of an object factory is tightly bound to the notion of an interface. According to the Gang of Four definition of the Factory Pattern we read that it should: …

Aug 28, 2008 · +1 for reminding us that Python documentation is always the best place to start our search for singleton and other design patterns.

Apr 17, 2009 · What is the difference between the Builder design pattern and the Factory design pattern? Which one is more advantageous and why ? How do I represent my findings as a graph if I want to test and compare/contrast these patterns ?

So my question: Do you happen to know of some good books/articles on workflow design patterns that I should read? Or am I trying to fit a square peg into a round hole, and you know of a completely different design pattern that I should know about? Or a python package that does what I want it to, regardless of the buzzwords it comes dressed up in?

Mar 5, 2022 · I have a proxy class with an underlying object. I wish to pass the proxy object to a function that expects and underlying object type. How do I make the proxy typing match the underlying object? cl...
