PyObjC
Encyclopedia
PyObjC is a bidirectional bridge between Python
and Objective-C
. It allows Python scripts to use and extend existing Objective-C class
libraries
.
PyObjC is commonly used to extend the Cocoa
libraries provided by Apple Computer
's Mac OS X, affording programmers the ability to write full featured Cocoa applications entirely in Python. By using BridgeSupport and libffi
, PyObjC can call any Mac OS X framework
. It also allows developers to use the powerful Python libraries while accessing Cocoa.
There is also rudimentary support for GNUstep
.
PyObjC 2.0 is now an integrated part of Mac OS X Leopard's Python distribution. Version 2.0 was included in Mac OS X 10.5.0, and version 2.0.1 was included in Mac OS X 10.5.2 .
