Here's a good function header given the following:
I wrote the below code

    def _FormatArg(arg):
        return FormatLogArgument(arg)
    args = [_FormatArg(arg) for arg in args]
    kwargs = {key: _FormatArg(value) for (key, value) in kwargs.items()}
    return ('(args=%s,    kwargs=%s)' % (args, kwargs))

What's a good function header?
