Florian Mayer added the comment: At least converting map(None, a, b, ...) to map(lambda *xs: xs, a, b, ...) I can understand if you prefer not to add the itertools.zip_longest workaround, although that would be the correct translation, of course. --

[issue7203] fixer for map(None, ...) needs to consider multi-argument case

New submission from Georg Brandl : Currently, ``map(None, a)`` is recognized and converted to ``list(a)`` which is correct but quite useless. ``map(None, a, b, ...)`` is not treated specially. An approximate translation would be ``map(lambda *xs: xs, a, b, ...)`` which however doesn't take into
