loops -> list/generator comprehensions

Sure Steve

Lemme see ... (indentation changed so comments associate with correct bits)

              for dirpath, _, filenames in os.walk('.')
              # This is getting tricky, whats the '_' for?  Which thing  
goes where again in a comprehension?

Yes, yes I do find it more difficult to read.  Maybe I just don't know  
python as well as I should (certainly not as well as others here!).  I  
guess it is just familiarity.  A single comprehension is ok, nesting them  
gets tricky, and 3 times is a strike for me.  I will practise :)

keep well
