I don't fully understand what your trying to do, but the most direct 
answer is 'no you cannot implement some methods of a class in python 
and others in Objective-C'.

Why do you want to do that in the first place? If you really want to 
include pure ObjC classes in your project you can use the 
Cocoa-Python-ObjC template.

Calling python methods from ObjC is easy enough if you use the right 
naming convention on the python side:

Python:
		def myMethodWithArg_andArg_(self, arg1, arg2):
			print arg1, arg2
			return 44

Objective-C:

		id result, arg1, arg2;

		result = [obj myMethodWithArg:arg1 andArg:arg2];

But as I wrote before: try to convert the entire example to Python, 
that makes your live much easier. And read the tutorials.
