Auto-generated documentation for EMRContainers type annotations stubs module mypy-boto3-emr-containers.

Client

Implicit type annotations

Can be used with boto3-stubs[emr-containers] package installed.

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

# EMRContainersClient usage example

from boto3.session import Session


session = Session()

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

1. client: EMRContainersClient
2. result: CancelJobRunResponseTypeDef

# ListJobRunsPaginator usage example

from boto3.session import Session


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

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

1. client: EMRContainersClient
2. paginator: ListJobRunsPaginator
3. item: ListJobRunsResponsePaginatorTypeDef

Explicit type annotations

With boto3-stubs-lite[emr-containers] or a standalone mypy_boto3_emr_containers package, you have to explicitly specify client: EMRContainersClient 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.

# EMRContainersClient usage example with type annotations

from boto3.session import Session

from mypy_boto3_emr_containers.client import EMRContainersClient
from mypy_boto3_emr_containers.type_defs import CancelJobRunResponseTypeDef
from mypy_boto3_emr_containers.type_defs import CancelJobRunRequestRequestTypeDef


session = Session()

client: EMRContainersClient = session.client("emr-containers")

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

# ListJobRunsPaginator usage example with type annotations

from boto3.session import Session

from mypy_boto3_emr_containers.client import EMRContainersClient
from mypy_boto3_emr_containers.paginator import ListJobRunsPaginator
from mypy_boto3_emr_containers.type_defs import ListJobRunsResponsePaginatorTypeDef


session = Session()
client: EMRContainersClient = session.client("emr-containers")

paginator: ListJobRunsPaginator = client.get_paginator("list_job_runs")
for item in paginator.paginate(...):
    item: ListJobRunsResponsePaginatorTypeDef
    print(item)
