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

    if verbose:
        _logger.info('loading    translation    file    for    language    %s', lang)
    env = odoo.api.Environment(cr, SUPERUSER_ID, (context or {}))

    Translation = env['ir.translation']
    try:
        if (not Lang.search_count([('code', '=', lang)])):
            Lang.load_lang(lang=lang, lang_name=lang_name)
        pot_reader = []
        fileobj.seek(0)
        if (fileformat == 'csv'):
            reader = csv.reader(fileobj, quotechar='"', delimiter=',')
            for row in reader:
                fields = row
                break
        elif (fileformat == 'po'):
            reader = PoFile(fileobj)
            fields = ['type', 'name', 'res_id', 'src', 'value', 'comments']
            if fileobj.name.endswith('.po'):
                try:
                    (addons_module_i18n, _ignored) = os.path.split(fileobj.name)
                    (addons_module, i18n_dir) = os.path.split(addons_module_i18n)
                    (addons, module) = os.path.split(addons_module)
                    pot_handle = file_open(os.path.join(addons, module, i18n_dir, (module + '.pot')))
                    pot_reader = PoFile(pot_handle)
                except:
                    pass
        else:

        pot_targets = defaultdict(Target)
        for (type, name, res_id, src, _ignored, comments) in pot_reader:
