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.

# 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

# 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.

# 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 CancelJobRunRequestRequestTypeDef


session = Session()

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

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

# 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)
