DeleteLexicon

The following Python code example uses the Amazon SDK for Python (Boto) to delete a lexicon in the region specified in your local Amazon configuration. The example deletes only the specified lexicon. It asks you to confirm that you want to proceed before actually deleting the lexicon.

The following code example uses default credentials stored in the Amazon SDK configuration file. For information about creating the configuration file, see Step 2.1: Set up the Amazon CLI.

For more information on this operation, see the reference for the DeleteLexicon API.
