ListLexicon

The following Python code example uses the Amazon SDK for Python (Boto) to list the lexicons in your account in the region specified in your local Amazon configuration. 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 ListLexicons API.

import sys

from boto3 import Session
from botocore.exceptions import BotoCoreError, ClientError

# Create a client using the credentials and region defined in the adminuser
# section of the Amazon credentials and configuration files
session = Session(profile_name="adminuser")
polly = session.client("polly")

try:
    # Request the list of available lexicons
    response = polly.list_lexicons()
except (BotoCoreError, ClientError) as error:
    # The service returned an error, exit gracefully
    print(error)
    sys.exit(-1)

# Get the list of lexicons in the response
lexicons = response.get("Lexicons", [])
print("{0} lexicon(s) found".format(len(lexicons)))

# Output a formatted list of lexicons with some of the attributes
for lexicon in lexicons:
    print((u" - {Name} ({Attributes[LanguageCode]}), "
           "{Attributes[LexemesCount]} lexeme(s)").format(**lexicon))
