Radostin Stoyanov b93cc3bbc9 pycodestyle: Do not use bare 'except:'
A bare 'except:' catches all exceptions [1], including SystemExit,
KeyboardInterrupt, and GeneratorExit (which is not an error and should
not normally be caught by user code). In situations where you need to
catch all “normal” errors, you can catch the base class for all normal
exceptions, Exception [2].
