How to use

Client annotations

CloudWatchLogsClient provides annotations for boto3.client("logs").

import boto3

from mypy_boto3_logs import CloudWatchLogsClient
from mypy_boto3_logs.paginator import (
    DescribeDestinationsPaginator,
    DescribeExportTasksPaginator,
    DescribeLogGroupsPaginator,
    DescribeLogStreamsPaginator,
    DescribeMetricFiltersPaginator,
    DescribeQueriesPaginator,
    DescribeResourcePoliciesPaginator,
    DescribeSubscriptionFiltersPaginator,
    FilterLogEventsPaginator,
)
from mypy_boto3_logs.type_defs import DestinationTypeDef, ...

client: CloudWatchLogsClient = boto3.client("logs")

# 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: CloudWatchLogsClient = session.client("logs")

Paginators annotations

mypy_boto3_logs.paginator module contains type annotations for all paginators.

client: CloudWatchLogsClient = boto3.client("logs")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
describe_destinations_paginator: DescribeDestinationsPaginator = client.get_paginator("describe_destinations")
describe_export_tasks_paginator: DescribeExportTasksPaginator = client.get_paginator("describe_export_tasks")
describe_log_groups_paginator: DescribeLogGroupsPaginator = client.get_paginator("describe_log_groups")
describe_log_streams_paginator: DescribeLogStreamsPaginator = client.get_paginator("describe_log_streams")
describe_metric_filters_paginator: DescribeMetricFiltersPaginator = client.get_paginator("describe_metric_filters")
describe_queries_paginator: DescribeQueriesPaginator = client.get_paginator("describe_queries")
describe_resource_policies_paginator: DescribeResourcePoliciesPaginator = client.get_paginator("describe_resource_policies")
describe_subscription_filters_paginator: DescribeSubscriptionFiltersPaginator = client.get_paginator("describe_subscription_filters")
filter_log_events_paginator: FilterLogEventsPaginator = client.get_paginator("filter_log_events")

Typed dictionations

mypy_boto3_logs.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_logs 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("logs")

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