I used autopep8 on some files and did carefully check the changes. I ignored E501,E302,E231,E225,E222,E221,E241,E203 in my search, and at least E501 on any autopep8 run. Other style fixes not related to PEP8: * Only use new-style classes. I don't think the usage of old-style classes was voluntary. Old-style classes are removed in Python 3. * Convert an if/else to a one-liner in mediawiki, change docstring style change to a comment something that wasn't really appropriate for a docstring. * Unneeded first if condition in meteofrance
