# GetLexicon
<a name="GetLexiconSamplePython"></a>

下列 Python 程式碼使用 適用於 Python (Boto) 的 AWS SDK 來擷取存放在 AWS 區域的所有語彙。此範例接受作為命令行參數的語彙名稱，並僅擷取該語彙，列印本機儲存的 tmp 路徑。

下列程式碼範例使用存放在 AWS SDK 組態檔案中的預設登入資料。如需建立組態檔的資訊，請參閱「[設定AWS CLI](setup-cli.md)」。

如需此操作的詳細資訊，請參閱 [https://docs.aws.amazon.com/polly/latest/dg/API_GetLexicon.html](https://docs.aws.amazon.com/polly/latest/dg/API_GetLexicon.html) API 的參考文章。
