How to use

Client annotations

ForecastServiceClient provides annotations for boto3.client("forecast").

import boto3

from mypy_boto3_forecast import ForecastServiceClient
from mypy_boto3_forecast.paginator import (
    ListDatasetGroupsPaginator,
    ListDatasetImportJobsPaginator,
    ListDatasetsPaginator,
    ListForecastExportJobsPaginator,
    ListForecastsPaginator,
    ListPredictorsPaginator,
)
from mypy_boto3_forecast.type_defs import CategoricalParameterRangeTypeDef, ...

client: ForecastServiceClient = boto3.client("forecast")

# now client usage is checked by mypy and IDE should provide code auto-complete

# works for session as well
session = boto3.session.Session(region="us-west-1")
session_client: ForecastServiceClient = session.client("forecast")

Paginators annotations

mypy_boto3_forecast.paginator module contains type annotations for all paginators.

client: ForecastServiceClient = boto3.client("forecast")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
list_dataset_groups_paginator: ListDatasetGroupsPaginator = client.get_paginator("list_dataset_groups")
list_dataset_import_jobs_paginator: ListDatasetImportJobsPaginator = client.get_paginator("list_dataset_import_jobs")
list_datasets_paginator: ListDatasetsPaginator = client.get_paginator("list_datasets")
list_forecast_export_jobs_paginator: ListForecastExportJobsPaginator = client.get_paginator("list_forecast_export_jobs")
list_forecasts_paginator: ListForecastsPaginator = client.get_paginator("list_forecasts")
list_predictors_paginator: ListPredictorsPaginator = client.get_paginator("list_predictors")

Typed dictionations

mypy_boto3_forecast.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

def get_structure() -> CategoricalParameterRangeTypeDef:
    return {
      ...
    }

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_forecast and other installed services.

# Run this command after you add or remove service packages
python -m mypy_boto3

Generated type annotations provide overloads for boto3.client and boto3.resource, boto3.Session.client and boto3.Session.resource functions, so explicit type annotations are not needed.

• mypy supports function overloads as expected
• PyCharm also supports function overloads, but consumes a lot of RAM, use carefully if you have many services installed
• VSCode does not currently support function overloads, use explicit type annotations

# Type is discovered correctly by mypy and PyCharm
# VSCode still needs explicit type annotations
client = boto3.client("forecast")

session_client = boto3.Session().client("forecast")
