How to use

Client annotations

AthenaClient provides annotations for boto3.client("athena").

import boto3

from mypy_boto3_athena import AthenaClient
from mypy_boto3_athena.paginator import (
    GetQueryResultsPaginator,
    ListDatabasesPaginator,
    ListDataCatalogsPaginator,
    ListNamedQueriesPaginator,
    ListQueryExecutionsPaginator,
    ListTableMetadataPaginator,
    ListTagsForResourcePaginator,
)
from mypy_boto3_athena.type_defs import ColumnInfoTypeDef, ...

client: AthenaClient = boto3.client("athena")

# 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: AthenaClient = session.client("athena")

Paginators annotations

mypy_boto3_athena.paginator module contains type annotations for all paginators.

client: AthenaClient = boto3.client("athena")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
get_query_results_paginator: GetQueryResultsPaginator = client.get_paginator("get_query_results")
list_data_catalogs_paginator: ListDataCatalogsPaginator = client.get_paginator("list_data_catalogs")
list_databases_paginator: ListDatabasesPaginator = client.get_paginator("list_databases")
list_named_queries_paginator: ListNamedQueriesPaginator = client.get_paginator("list_named_queries")
list_query_executions_paginator: ListQueryExecutionsPaginator = client.get_paginator("list_query_executions")
list_table_metadata_paginator: ListTableMetadataPaginator = client.get_paginator("list_table_metadata")
list_tags_for_resource_paginator: ListTagsForResourcePaginator = client.get_paginator("list_tags_for_resource")

Typed dictionations

mypy_boto3_athena.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_athena 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("athena")

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