Just a quick report on trying this out: 

On first try it didn't appear to be working but it works fine now
that I figured out the "gotchas" :

 Console output is just output -- there's no "listener window". 
 Instead use "New" from the file menu, type python commands in 
 the window and click "run" .  ( BTW: What's the other button 
  mean ? "DNGN" ? ) 


 Since it's running as a file, it doesn't echo returned values -- 
 you need to explicitly print the values. 


 'RUN' doesn't seem to run them as __main__ . None of my scripts
 seemed to work until, for example, after the line: 
	if __name__ == '__main__' : main()
 I added:
	else: main()


 My Nib loading code didn't appear to work any better under Toxic Edit 
 than under Terminal.app command lines. 


 Since it uses the normal "/use/local/lib/python2.1"  paths, it was 
 able to see and import  my previously installed ObjC & Carbon 
 modules.  ( Eventually, we ought to figure out how to make a real
 Python.framework! )

  Thanks. 

  I had started to look at the NSText* docs in AppKit just before you 
  posted this -- I was thinking along the same lines, and I was trying
  to figure out one of the missing pieces in your code -- how to grab
  a line after <RETURN> and make an in/out console window. 

  I'm going to take a peek at your sources next and see if I can 
  catch up! 

  FYI: The following code works fine from Toxic Edit with ObjC 
  installed.  -- Steve. 

 (PS. I just set up an iDisk & home page at mac.com. 
   I'm going to put  binaries on ObjCmodule.so & Carbonmodule.so   
   there for folks who don't want  to attempt the whole build. )
