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

Client

Implicit type annotations

Can be used with types-aioboto3[emr] package installed.

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

# EMRClient usage example

from aioboto3.session import Session


session = Session()

async with session.client("emr") as client:  # (1)
    result = await client.add_instance_fleet()  # (2)

1. client: EMRClient
2. result: AddInstanceFleetOutputTypeDef

# ListBootstrapActionsPaginator usage example

from aioboto3.session import Session


session = Session()

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

1. client: EMRClient
2. paginator: ListBootstrapActionsPaginator
3. item: ListBootstrapActionsOutputTypeDef

# ClusterRunningWaiter usage example

from aioboto3.session import Session


session = Session()

async with session.client("emr") as client:  # (1)
    waiter = client.get_waiter("cluster_running")  # (2)
    await waiter.wait()

1. client: EMRClient
2. waiter: ClusterRunningWaiter

Explicit type annotations

With types-aioboto3-lite[emr] or a standalone types_aiobotocore_emr package, you have to explicitly specify client: EMRClient 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.

# EMRClient usage example with type annotations

from aioboto3.session import Session

from types_aiobotocore_emr.client import EMRClient
from types_aiobotocore_emr.type_defs import AddInstanceFleetOutputTypeDef
from types_aiobotocore_emr.type_defs import AddInstanceFleetInputRequestTypeDef


session = Session()

client: EMRClient
async with session.client("emr") as client:  # (1)
    kwargs: AddInstanceFleetInputRequestTypeDef = {...}  # (2)
    result: AddInstanceFleetOutputTypeDef = await client.add_instance_fleet(**kwargs)  # (3)

1. client: EMRClient
2. kwargs: AddInstanceFleetInputRequestTypeDef
3. result: AddInstanceFleetOutputTypeDef

# ListBootstrapActionsPaginator usage example with type annotations

from aioboto3.session import Session

from types_aiobotocore_emr.client import EMRClient
from types_aiobotocore_emr.paginator import ListBootstrapActionsPaginator
from types_aiobotocore_emr.type_defs import ListBootstrapActionsOutputTypeDef


session = Session()

client: EMRClient
async with session.client("emr") as client:  # (1)
    paginator: ListBootstrapActionsPaginator = client.get_paginator("list_bootstrap_actions")  # (2)
    async for item in paginator.paginate(...):
        item: ListBootstrapActionsOutputTypeDef
        print(item)  # (3)

1. client: EMRClient
2. paginator: ListBootstrapActionsPaginator
3. item: ListBootstrapActionsOutputTypeDef

# ClusterRunningWaiter usage example with type annotations

from aioboto3.session import Session

from types_aiobotocore_emr.client import EMRClient
from types_aiobotocore_emr.waiter import ClusterRunningWaiter


session = Session()

async with session.client("emr") as client:  # (1)
    waiter = client.get_waiter("cluster_running")  # (2)
    await waiter.wait()

1. client: EMRClient
2. waiter: ClusterRunningWaiter
