Writing Cocoa Applications In Python 3

It looks like PyObjC is not ported to Python 3 yet. Meanwhile is there a way to write Cocoa applications using Python 3? I am intending to start a new MacOSX GUI application projec

Solution 1:

For full-blown Cocoa, I think PyObjC is pretty much the only game in town. If you are coming to Cocoa from a Python background rather than to Python from an Obj-C Cocoa background, surely the learning curve of the Cocoa APIs is much steeper than the differences between Python 2.x and Python 3.x. So I think, at the moment, the best strategy is writing your app in Python 2.x while trying to make it as Python 3.x friendly as possible, including periodically running 2to3 on it as a check. And I'm sure patches for PyObjC to help with Python 3 support would be very welcome. If you are just looking for simple GUI interfaces rather than a full-blown Cocoa app, you might be able to get by with calls out to other packages like CocoaDialog or a Python 2.x-PyObjC dialog app :=)
