Oops. I meant the following: Instead of testing: if not ''.join(lines).strip(): the new code now tests: if all([z.isspace() for z in lines]): This makes the gain in efficiency all the clearer. The former generates *two* new strings which the GC must then deal with. Edward -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
