How to use

Client annotations

CloudFormationClient provides annotations for boto3.client("cloudformation").

import boto3

from mypy_boto3_cloudformation import CloudFormationClient, CloudFormationServiceResource
from mypy_boto3_cloudformation.paginator import (
    DescribeAccountLimitsPaginator,
    DescribeChangeSetPaginator,
    DescribeStackEventsPaginator,
    DescribeStacksPaginator,
    ListChangeSetsPaginator,
    ListExportsPaginator,
    ListImportsPaginator,
    ListStackInstancesPaginator,
    ListStackResourcesPaginator,
    ListStackSetOperationResultsPaginator,
    ListStackSetOperationsPaginator,
    ListStackSetsPaginator,
    ListStacksPaginator,
)
from mypy_boto3_cloudformation.service_resource import (
    Event,
    ServiceResourceStacksCollection,
    Stack,
    StackResource,
    StackResourceSummary,
)
from mypy_boto3_cloudformation.type_defs import AccountGateResultTypeDef, ...
from mypy_boto3_cloudformation.waiter import (
    ChangeSetCreateCompleteWaiter,
    StackCreateCompleteWaiter,
    StackDeleteCompleteWaiter,
    StackExistsWaiter,
    StackImportCompleteWaiter,
    StackRollbackCompleteWaiter,
    StackUpdateCompleteWaiter,
    TypeRegistrationCompleteWaiter,
)

client: CloudFormationClient = boto3.client("cloudformation")

# 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: CloudFormationClient = session.client("cloudformation")

Paginators annotations

mypy_boto3_cloudformation.paginator module contains type annotations for all paginators.

client: CloudFormationClient = boto3.client("cloudformation")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
describe_account_limits_paginator: DescribeAccountLimitsPaginator = client.get_paginator("describe_account_limits")
describe_change_set_paginator: DescribeChangeSetPaginator = client.get_paginator("describe_change_set")
describe_stack_events_paginator: DescribeStackEventsPaginator = client.get_paginator("describe_stack_events")
describe_stacks_paginator: DescribeStacksPaginator = client.get_paginator("describe_stacks")
list_change_sets_paginator: ListChangeSetsPaginator = client.get_paginator("list_change_sets")
list_exports_paginator: ListExportsPaginator = client.get_paginator("list_exports")
list_imports_paginator: ListImportsPaginator = client.get_paginator("list_imports")
list_stack_instances_paginator: ListStackInstancesPaginator = client.get_paginator("list_stack_instances")
list_stack_resources_paginator: ListStackResourcesPaginator = client.get_paginator("list_stack_resources")
list_stack_set_operation_results_paginator: ListStackSetOperationResultsPaginator = client.get_paginator("list_stack_set_operation_results")
list_stack_set_operations_paginator: ListStackSetOperationsPaginator = client.get_paginator("list_stack_set_operations")
list_stack_sets_paginator: ListStackSetsPaginator = client.get_paginator("list_stack_sets")
list_stacks_paginator: ListStacksPaginator = client.get_paginator("list_stacks")

Waiters annotations

mypy_boto3_cloudformation.waiter module contains type annotations for all waiters.

client: CloudFormationClient = boto3.client("cloudformation")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
change_set_create_complete_waiter: ChangeSetCreateCompleteWaiter = client.get_waiter("change_set_create_complete")
stack_create_complete_waiter: StackCreateCompleteWaiter = client.get_waiter("stack_create_complete")
stack_delete_complete_waiter: StackDeleteCompleteWaiter = client.get_waiter("stack_delete_complete")
stack_exists_waiter: StackExistsWaiter = client.get_waiter("stack_exists")
stack_import_complete_waiter: StackImportCompleteWaiter = client.get_waiter("stack_import_complete")
stack_rollback_complete_waiter: StackRollbackCompleteWaiter = client.get_waiter("stack_rollback_complete")
stack_update_complete_waiter: StackUpdateCompleteWaiter = client.get_waiter("stack_update_complete")
type_registration_complete_waiter: TypeRegistrationCompleteWaiter = client.get_waiter("type_registration_complete")

Service Resource annotations

CloudFormationServiceResource provides annotations for boto3.resource("cloudformation").

resource: CloudFormationServiceResource = boto3.resource("cloudformation")

# now resource 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_resource: CloudFormationServiceResource = session.resource("cloudformation")

Other resources annotations

mypy_boto3_cloudformation.service_resource module contains type annotations for all resources.

resource: CloudFormationServiceResource = boto3.resource("cloudformation")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
my_event: Event = resource.Event(...)
my_stack: Stack = resource.Stack(...)
my_stack_resource: StackResource = resource.StackResource(...)
my_stack_resource_summary: StackResourceSummary = resource.StackResourceSummary(...)

Collections annotations

mypy_boto3_cloudformation.service_resource module contains type annotations for all CloudFormationServiceResource collections.

resource: CloudFormationServiceResource = boto3.resource("cloudformation")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
stacks: cloudformation_resources.ServiceResourceStacksCollection = resource.stacks

Typed dictionations

mypy_boto3_cloudformation.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_cloudformation 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("cloudformation")
resource = boto3.resource("cloudformation")

session_client = boto3.Session().client("cloudformation")
session_resource = boto3.Session().resource("cloudformation")
