How to use

Client annotations

NeptuneClient provides annotations for boto3.client("neptune").

import boto3

from mypy_boto3_neptune import NeptuneClient
from mypy_boto3_neptune.paginator import (
    DescribeDBClusterParameterGroupsPaginator,
    DescribeDBClusterParametersPaginator,
    DescribeDBClusterSnapshotsPaginator,
    DescribeDBClustersPaginator,
    DescribeDBEngineVersionsPaginator,
    DescribeDBInstancesPaginator,
    DescribeDBParameterGroupsPaginator,
    DescribeDBParametersPaginator,
    DescribeDBSubnetGroupsPaginator,
    DescribeEngineDefaultParametersPaginator,
    DescribeEventsPaginator,
    DescribeEventSubscriptionsPaginator,
    DescribeOrderableDBInstanceOptionsPaginator,
    DescribePendingMaintenanceActionsPaginator,
)
from mypy_boto3_neptune.type_defs import AvailabilityZoneTypeDef, ...
from mypy_boto3_neptune.waiter import DBInstanceAvailableWaiter, DBInstanceDeletedWaiter

client: NeptuneClient = boto3.client("neptune")

# 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: NeptuneClient = session.client("neptune")

Paginators annotations

mypy_boto3_neptune.paginator module contains type annotations for all paginators.

client: NeptuneClient = boto3.client("neptune")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
describe_db_cluster_parameter_groups_paginator: DescribeDBClusterParameterGroupsPaginator = client.get_paginator("describe_db_cluster_parameter_groups")
describe_db_cluster_parameters_paginator: DescribeDBClusterParametersPaginator = client.get_paginator("describe_db_cluster_parameters")
describe_db_cluster_snapshots_paginator: DescribeDBClusterSnapshotsPaginator = client.get_paginator("describe_db_cluster_snapshots")
describe_db_clusters_paginator: DescribeDBClustersPaginator = client.get_paginator("describe_db_clusters")
describe_db_engine_versions_paginator: DescribeDBEngineVersionsPaginator = client.get_paginator("describe_db_engine_versions")
describe_db_instances_paginator: DescribeDBInstancesPaginator = client.get_paginator("describe_db_instances")
describe_db_parameter_groups_paginator: DescribeDBParameterGroupsPaginator = client.get_paginator("describe_db_parameter_groups")
describe_db_parameters_paginator: DescribeDBParametersPaginator = client.get_paginator("describe_db_parameters")
describe_db_subnet_groups_paginator: DescribeDBSubnetGroupsPaginator = client.get_paginator("describe_db_subnet_groups")
describe_engine_default_parameters_paginator: DescribeEngineDefaultParametersPaginator = client.get_paginator("describe_engine_default_parameters")
describe_event_subscriptions_paginator: DescribeEventSubscriptionsPaginator = client.get_paginator("describe_event_subscriptions")
describe_events_paginator: DescribeEventsPaginator = client.get_paginator("describe_events")
describe_orderable_db_instance_options_paginator: DescribeOrderableDBInstanceOptionsPaginator = client.get_paginator("describe_orderable_db_instance_options")
describe_pending_maintenance_actions_paginator: DescribePendingMaintenanceActionsPaginator = client.get_paginator("describe_pending_maintenance_actions")

Waiters annotations

mypy_boto3_neptune.waiter module contains type annotations for all waiters.

client: NeptuneClient = boto3.client("neptune")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
db_instance_available_waiter: DBInstanceAvailableWaiter = client.get_waiter("db_instance_available")
db_instance_deleted_waiter: DBInstanceDeletedWaiter = client.get_waiter("db_instance_deleted")

Typed dictionations

mypy_boto3_neptune.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_neptune 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("neptune")

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