Copying text via Python on OS X (revisited)

Let's try that again.

import Cocoa
pb = Cocoa.NSPasteboard.generalPasteboard()

def get_clipboard_text():
    """Get the text contents of the system clipboard. 
    @return (string)
    """
    return pb.stringForType_(Cocoa.NSPasteboardTypeString)


def copy_text_to_clipboard(text):
    """Copy the supplied text to the clipboard.
    @param text
    """
    pb.declareTypes_owner_([Cocoa.NSPasteboardTypeString], None)
    pb.setString_forType_(text, Cocoa.NSPasteboardTypeString)
