Generated by mypy-boto3-buider 2.1.0.

More information can be found on boto3-stubs page.

How to install

Make sure you have mypy installed and activated in your IDE.

Install boto3-stubs for DAX service.

python -m pip install boto3-stubs[dax]

How to use

Client annotations

DAXClient provides annotations for boto3.client("dax").

import boto3

from mypy_boto3_dax import DAXClient

client: DAXClient = boto3.client("dax")

# 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: DAXClient = session.client("dax")

Paginators annotations

mypy_boto3_dax.paginator module contains type annotations for all paginators.

from mypy_boto3_dax import DAXClient
from mypy_boto3_dax.paginator import (
    DescribeClustersPaginator,
    DescribeDefaultParametersPaginator,
    DescribeEventsPaginator,
    DescribeParameterGroupsPaginator,
    DescribeParametersPaginator,
    DescribeSubnetGroupsPaginator,
    ListTagsPaginator,
)

client: DAXClient = boto3.client("dax")

# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
describe_clusters_paginator: DescribeClustersPaginator = client.get_paginator("describe_clusters")
describe_default_parameters_paginator: DescribeDefaultParametersPaginator = client.get_paginator("describe_default_parameters")
describe_events_paginator: DescribeEventsPaginator = client.get_paginator("describe_events")
describe_parameter_groups_paginator: DescribeParameterGroupsPaginator = client.get_paginator("describe_parameter_groups")
describe_parameters_paginator: DescribeParametersPaginator = client.get_paginator("describe_parameters")
describe_subnet_groups_paginator: DescribeSubnetGroupsPaginator = client.get_paginator("describe_subnet_groups")
list_tags_paginator: ListTagsPaginator = client.get_paginator("list_tags")

Typed dictionations

mypy_boto3_dax.type_defs module contains structures and shapes assembled to typed dictionaries for additional type checking.

from mypy_boto3_dax.type_defs import ClusterTypeDef, ...

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

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_dax 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

import boto3

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

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