How to use

Client annotations

BatchClient provides annotations for boto3.client("batch").

import boto3

from mypy_boto3_batch import BatchClient
from mypy_boto3_batch.paginator import (
    DescribeComputeEnvironmentsPaginator,
    DescribeJobDefinitionsPaginator,
    DescribeJobQueuesPaginator,
    ListJobsPaginator,
)
from mypy_boto3_batch.type_defs import ArrayPropertiesDetailTypeDef, ...

client: BatchClient = boto3.client("batch")

# 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: BatchClient = session.client("batch")

Paginators annotations

mypy_boto3_batch.paginator module contains type annotations for all paginators.

client: BatchClient = boto3.client("batch")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
describe_compute_environments_paginator: DescribeComputeEnvironmentsPaginator = client.get_paginator("describe_compute_environments")
describe_job_definitions_paginator: DescribeJobDefinitionsPaginator = client.get_paginator("describe_job_definitions")
describe_job_queues_paginator: DescribeJobQueuesPaginator = client.get_paginator("describe_job_queues")
list_jobs_paginator: ListJobsPaginator = client.get_paginator("list_jobs")

Typed dictionations

mypy_boto3_batch.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_batch 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("batch")

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