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

Client

Implicit type annotations

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

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

# EMRServerlessClient usage example

from aiobotocore.session import get_session


session = get_session()

async with session.create_client("emr-serverless") as client:  # (1)
    result = await client.cancel_job_run()  # (2)

1. client: EMRServerlessClient
2. result: CancelJobRunResponseTypeDef

# ListApplicationsPaginator usage example

from aiobotocore.session import get_session


session = get_session()

async with session.create_client("emr-serverless") as client:  # (1)
    paginator = client.get_paginator("list_applications")  # (2)
    async for item in paginator.paginate(...):
        print(item)  # (3)

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

Explicit type annotations

With types-aiobotocore-lite[emr-serverless] or a standalone types_aiobotocore_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.

# EMRServerlessClient usage example with type annotations

from aiobotocore.session import get_session

from types_aiobotocore_emr_serverless.client import EMRServerlessClient
from types_aiobotocore_emr_serverless.type_defs import CancelJobRunResponseTypeDef
from types_aiobotocore_emr_serverless.type_defs import CancelJobRunRequestRequestTypeDef


session = get_session()

async with session.create_client("emr-serverless") as client:
    client: EMRServerlessClient
    kwargs: CancelJobRunRequestRequestTypeDef = {...}
    result: CancelJobRunResponseTypeDef = await client.cancel_job_run(**kwargs)

# ListApplicationsPaginator usage example with type annotations

from aiobotocore.session import get_session

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


session = get_session()

async with session.create_client("emr-serverless") as client:
    client: EMRServerlessClient
    paginator: ListApplicationsPaginator = client.get_paginator("list_applications")
    async for item in paginator.paginate(...):
        item: ListApplicationsResponseTypeDef
        print(item)
