Examples
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.
Client usage example
from aioboto3.session import Session
session = Session()
async with session.client("emr") as client: # (1)
result = await client.add_instance_fleet() # (2)
- client: EMRClient
- result: AddInstanceFleetOutputTypeDef
Paginator 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)
- client: EMRClient
- paginator: ListBootstrapActionsPaginator
- item: ListBootstrapActionsOutputTypeDef
Waiter 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()
- client: EMRClient
- 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.
Client usage example
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)
- client: EMRClient
- kwargs: AddInstanceFleetInputRequestTypeDef
- result: AddInstanceFleetOutputTypeDef
Paginator usage example
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)
- client: EMRClient
- paginator: ListBootstrapActionsPaginator
- item: ListBootstrapActionsOutputTypeDef
Waiter usage example
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()
- client: EMRClient
- waiter: ClusterRunningWaiter
