How to use

Client annotations

MigrationHubClient provides annotations for boto3.client("mgh").

import boto3

from mypy_boto3_mgh import MigrationHubClient
from mypy_boto3_mgh.paginator import (
    ListApplicationStatesPaginator,
    ListCreatedArtifactsPaginator,
    ListDiscoveredResourcesPaginator,
    ListMigrationTasksPaginator,
    ListProgressUpdateStreamsPaginator,
)
from mypy_boto3_mgh.type_defs import ApplicationStateTypeDef, ...

client: MigrationHubClient = boto3.client("mgh")

# 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: MigrationHubClient = session.client("mgh")

Paginators annotations

mypy_boto3_mgh.paginator module contains type annotations for all paginators.

client: MigrationHubClient = boto3.client("mgh")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
list_application_states_paginator: ListApplicationStatesPaginator = client.get_paginator("list_application_states")
list_created_artifacts_paginator: ListCreatedArtifactsPaginator = client.get_paginator("list_created_artifacts")
list_discovered_resources_paginator: ListDiscoveredResourcesPaginator = client.get_paginator("list_discovered_resources")
list_migration_tasks_paginator: ListMigrationTasksPaginator = client.get_paginator("list_migration_tasks")
list_progress_update_streams_paginator: ListProgressUpdateStreamsPaginator = client.get_paginator("list_progress_update_streams")

Typed dictionations

mypy_boto3_mgh.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_mgh 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("mgh")

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