Cocoa (OS X) vs Pyramid: What are the differences?
Developers describe Cocoa (OS X) as "The Cocoa frameworks consist of libraries, APIs, and runtimes that form the development layer for all of OS X". Much of Cocoa is implemented in Objective-C, an object-oriented language that is compiled to run at incredible speed, yet employs a truly dynamic runtime making it uniquely flexible. Because Objective-C is a superset of C, it is easy to mix C and even C++ into your Cocoa applications. On the other hand, Pyramid is detailed as "A framework for building Python web applications". It makes it easy to write web applications. You can start small with this "hello world" minimal request/response web app. This may take you far, especially while learning. As your application grows, it offers many features that make writing complex software take less effort.
Cocoa (OS X) and Pyramid can be primarily classified as "Frameworks (Full Stack)" tools.
