# PutLexicon
<a name="PutLexiconSamplePython"></a>

以下代码示例显示如何使用基于 Python (boto3) 的应用程序将发音词典存储在 AWS 区域中。

有关此操作的更多信息，请参阅 [https://docs.aws.amazon.com/polly/latest/dg/API_PutLexicon.html](https://docs.aws.amazon.com/polly/latest/dg/API_PutLexicon.html) API 参考。

请注意以下几点：
+ 您需要通过提供本地词典文件名和存储词典名更新该代码。
+ 该示例假定您拥有在名为 `pls` 的子目录中创建的词典文件。您需要视情况新路径。

以下代码示例使用存储在 AWS 软件开发工具包配置文件中的默认凭证。有关创建配置文件的信息，请参阅 [设置AWS CLI](setup-cli.md)。
