Auto-generated documentation for EMRServerless type annotations stubs module types-boto3-emr-serverless.

Client

Implicit type annotations

Can be used with types-boto3[emr-serverless] package installed.

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

Client method usage example

# EMRServerlessClient usage example

from boto3.session import Session


session = Session()

client = session.client("emr-serverless")  # (1)
result = client.cancel_job_run()  # (2)

1. client: EMRServerlessClient
2. result: CancelJobRunResponseTypeDef

Paginator usage example

# ListApplicationsPaginator usage example

from boto3.session import Session


session = Session()
client = session.client("emr-serverless")  # (1)

paginator = client.get_paginator("list_applications")  # (2)
for item in paginator.paginate(...):
    print(item)  # (3)

1. client: EMRServerlessClient
2. paginator: ListApplicationsPaginator
3. item: ListApplicationsResponseTypeDef

Explicit type annotations

With types-boto3-lite[emr-serverless] or a standalone types_boto3_emr_serverless package, you have to explicitly specify client: EMRServerlessClient 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 method usage example

# EMRServerlessClient usage example with type annotations

from boto3.session import Session

from types_boto3_emr_serverless.client import EMRServerlessClient
from types_boto3_emr_serverless.type_defs import CancelJobRunResponseTypeDef
from types_boto3_emr_serverless.type_defs import CancelJobRunRequestTypeDef


session = Session()

client: EMRServerlessClient = session.client("emr-serverless")

kwargs: CancelJobRunRequestTypeDef = {...}
result: CancelJobRunResponseTypeDef = client.cancel_job_run(**kwargs)

Paginator usage example

# ListApplicationsPaginator usage example with type annotations

from boto3.session import Session

from types_boto3_emr_serverless.client import EMRServerlessClient
from types_boto3_emr_serverless.paginator import ListApplicationsPaginator
from types_boto3_emr_serverless.type_defs import ListApplicationsResponseTypeDef


session = Session()
client: EMRServerlessClient = session.client("emr-serverless")

paginator: ListApplicationsPaginator = client.get_paginator("list_applications")
for item in paginator.paginate(...):
    item: ListApplicationsResponseTypeDef
    print(item)
