From 0032ccbd60f202ec76d9b738cddc8bdbf9f54133 Mon Sep 17 00:00:00 2001 From: Richard Maw Date: Tue, 31 Jul 2012 12:52:12 +0000 Subject: python scripts: pep8ize codebase This was done with the aid of the pep8 script, available by running `easy_install pep8`. It may be worth making this part of ./check, but that will require putting pep8 into the development tools stratum. This should be easy, given pep8 has no external dependencies. --- morphlib/savefile.py | 25 ++++++++++++------------- 1 file changed, 12 insertions(+), 13 deletions(-) (limited to 'morphlib/savefile.py') diff --git a/morphlib/savefile.py b/morphlib/savefile.py index 9392f1a2..2d87a54f 100644 --- a/morphlib/savefile.py +++ b/morphlib/savefile.py @@ -1,14 +1,14 @@ # Copyright (C) 2012 Codethink Limited -# +# # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; version 2 of the License. -# +# # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
