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

    def GlobalStyles():
        for (style, _) in _DEFAULT_STYLE_TO_FACTORY:
            (yield style)
    def_style = False
    if (style_config is None):
        for style in GlobalStyles():
            if (_style == style):
                def_style = True
                break
        if (not def_style):
            return _style
        return _GLOBAL_STYLE_FACTORY()
    if isinstance(style_config, dict):
        config = _CreateConfigParserFromConfigDict(style_config)
    elif isinstance(style_config, str):
        style_factory = _STYLE_NAME_TO_FACTORY.get(style_config.lower())
        if (style_factory is not None):
            return style_factory()
        if style_config.startswith('{'):
            config = _CreateConfigParserFromConfigString(style_config)
        else:
            config = _CreateConfigParserFromConfigFile(style_config)
    return _CreateStyleFromConfigParser(config)

What's a good function header?
