How to use

Client annotations

EMRClient provides annotations for boto3.client("emr").

import boto3

from mypy_boto3_emr import EMRClient
from mypy_boto3_emr.paginator import (
    ListBootstrapActionsPaginator,
    ListClustersPaginator,
    ListInstanceFleetsPaginator,
    ListInstanceGroupsPaginator,
    ListInstancesPaginator,
    ListSecurityConfigurationsPaginator,
    ListStepsPaginator,
)
from mypy_boto3_emr.type_defs import ApplicationTypeDef, ...
from mypy_boto3_emr.waiter import ClusterRunningWaiter, ClusterTerminatedWaiter, StepCompleteWaiter

client: EMRClient = boto3.client("emr")

# 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: EMRClient = session.client("emr")

Paginators annotations

mypy_boto3_emr.paginator module contains type annotations for all paginators.

client: EMRClient = boto3.client("emr")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
list_bootstrap_actions_paginator: ListBootstrapActionsPaginator = client.get_paginator("list_bootstrap_actions")
list_clusters_paginator: ListClustersPaginator = client.get_paginator("list_clusters")
list_instance_fleets_paginator: ListInstanceFleetsPaginator = client.get_paginator("list_instance_fleets")
list_instance_groups_paginator: ListInstanceGroupsPaginator = client.get_paginator("list_instance_groups")
list_instances_paginator: ListInstancesPaginator = client.get_paginator("list_instances")
list_security_configurations_paginator: ListSecurityConfigurationsPaginator = client.get_paginator("list_security_configurations")
list_steps_paginator: ListStepsPaginator = client.get_paginator("list_steps")

Waiters annotations

mypy_boto3_emr.waiter module contains type annotations for all waiters.

client: EMRClient = boto3.client("emr")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
cluster_running_waiter: ClusterRunningWaiter = client.get_waiter("cluster_running")
cluster_terminated_waiter: ClusterTerminatedWaiter = client.get_waiter("cluster_terminated")
step_complete_waiter: StepCompleteWaiter = client.get_waiter("step_complete")

Typed dictionations

mypy_boto3_emr.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_emr 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("emr")

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