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

    clear_cache()
    full_dict = get_full_dict(lang)
    def restore_newlines(s):
        return s.replace(u'|||||', u'\\\n').replace(u'|    |    |    |    |', u'\\\n').replace(u'||||', u'\\n').replace(u'|    |    |    |', u'\\n').replace(u'|||', u'\n').replace(u'|    |    |', u'\n')
    translation_dict = {}
    for (key, value) in zip(frappe.get_file_items(untranslated_file, ignore_empty_lines=False), frappe.get_file_items(translated_file, ignore_empty_lines=False)):
        translation_dict[restore_newlines(key)] = restore_newlines(value)
    full_dict.update(translation_dict)
    for app in frappe.get_all_apps(True):
        write_translations_file(app, lang, full_dict)

What's a good function header?
