How to use

Client annotations

SWFClient provides annotations for boto3.client("swf").

import boto3

from mypy_boto3_swf import SWFClient
from mypy_boto3_swf.paginator import (
    GetWorkflowExecutionHistoryPaginator,
    ListActivityTypesPaginator,
    ListClosedWorkflowExecutionsPaginator,
    ListDomainsPaginator,
    ListOpenWorkflowExecutionsPaginator,
    ListWorkflowTypesPaginator,
    PollForDecisionTaskPaginator,
)
from mypy_boto3_swf.type_defs import ActivityTaskCancelRequestedEventAttributesTypeDef, ...

client: SWFClient = boto3.client("swf")

# now client usage is checked by mypy and IDE should provide code auto-complete

# works for session as well
session = boto3.session.Session(region="us-west-1")
session_client: SWFClient = session.client("swf")

Paginators annotations

mypy_boto3_swf.paginator module contains type annotations for all paginators.

client: SWFClient = boto3.client("swf")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
get_workflow_execution_history_paginator: GetWorkflowExecutionHistoryPaginator = client.get_paginator("get_workflow_execution_history")
list_activity_types_paginator: ListActivityTypesPaginator = client.get_paginator("list_activity_types")
list_closed_workflow_executions_paginator: ListClosedWorkflowExecutionsPaginator = client.get_paginator("list_closed_workflow_executions")
list_domains_paginator: ListDomainsPaginator = client.get_paginator("list_domains")
list_open_workflow_executions_paginator: ListOpenWorkflowExecutionsPaginator = client.get_paginator("list_open_workflow_executions")
list_workflow_types_paginator: ListWorkflowTypesPaginator = client.get_paginator("list_workflow_types")
poll_for_decision_task_paginator: PollForDecisionTaskPaginator = client.get_paginator("poll_for_decision_task")

Typed dictionations

mypy_boto3_swf.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

def get_structure() -> ActivityTaskCancelRequestedEventAttributesTypeDef:
    return {
      ...
    }

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_swf and other installed services.

# Run this command after you add or remove service packages
python -m mypy_boto3

Generated type annotations provide overloads for boto3.client and boto3.resource, boto3.Session.client and boto3.Session.resource functions, so explicit type annotations are not needed.

• mypy supports function overloads as expected
• PyCharm also supports function overloads, but consumes a lot of RAM, use carefully if you have many services installed
• VSCode does not currently support function overloads, use explicit type annotations

# Type is discovered correctly by mypy and PyCharm
# VSCode still needs explicit type annotations
client = boto3.client("swf")

session_client = boto3.Session().client("swf")
