Auto-generated documentation for Polly type annotations stubs module mypy-boto3-polly.

Client

Implicit type annotations

Can be used with boto3-stubs[polly] package installed.

Write your Polly code as usual, type checking and code completion should work out of the box.

Client usage example
from boto3.session import Session


session = Session()

client = session.client("polly")  # (1)
result = client.describe_voices()  # (2)
  1. client: PollyClient
  2. result: DescribeVoicesOutputTypeDef
Paginator usage example
from boto3.session import Session


session = Session()
client = session.client("polly")  # (1)

paginator = client.get_paginator("describe_voices")  # (2)
for item in paginator.paginate(...):
    print(item)  # (3)
  1. client: PollyClient
  2. paginator: DescribeVoicesPaginator
  3. item: DescribeVoicesOutputTypeDef

Explicit type annotations

With boto3-stubs-lite[polly] or a standalone mypy_boto3_polly package, you have to explicitly specify client: PollyClient type annotation.

All other type annotations are optional, as types should be discovered automatically. However, these type annotations can be helpful in your functions and methods.

Client usage example
from boto3.session import Session

from mypy_boto3_polly.client import PollyClient
from mypy_boto3_polly.type_defs import DescribeVoicesOutputTypeDef
from mypy_boto3_polly.type_defs import DescribeVoicesInputRequestTypeDef


session = Session()

client: PollyClient = session.client("polly")

kwargs: DescribeVoicesInputRequestTypeDef = {...}
result: DescribeVoicesOutputTypeDef = client.describe_voices(**kwargs)
Paginator usage example
from boto3.session import Session

from mypy_boto3_polly.client import PollyClient
from mypy_boto3_polly.paginator import DescribeVoicesPaginator
from mypy_boto3_polly.type_defs import DescribeVoicesOutputTypeDef


session = Session()
client: PollyClient = session.client("polly")

paginator: DescribeVoicesPaginator = client.get_paginator("describe_voices")
for item in paginator.paginate(...):
    item: DescribeVoicesOutputTypeDef
    print(item)
