# DeleteLexicon
<a name="DeleteLexiconPython"></a>

以下 Python 代码示例使用AWS SDK for Python (Boto) 删除在本地 AWS 配置中指定的区域中的词典。该示例只删除指定的词典。在实际删除词典前，它会要求您确认要继续操作。

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)。

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