Type annotations for boto3.Lambda 1.13.26 service compatible with mypy, VSCode, PyCharm and other tools.

Generated by mypy-boto3-buider 2.0.4.

More information can be found on boto3-stubs page.

How to use

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

Install boto3-stubs for Lambda service.

python -m pip install boto3-stubs[lambda]

Use boto3 with mypy_boto3_lambda in your project and enjoy type checking and auto-complete.

import boto3

from mypy_boto3_lambda import LambdaClient

# Now mypy can check if your code is valid.
client: LambdaClient = boto3.client("lambda")

# works for session as well
session = boto3.session.Session(region="us-west-1")
session_client: LambdaClient = session.client("lambda")



# Waiters are also supported

import mypy_boto3_lambda.waiter as lambda_waiters

function_active_waiter: lambda_waiters.FunctionActiveWaiter = client.get_waiter("function_active")
function_exists_waiter: lambda_waiters.FunctionExistsWaiter = client.get_waiter("function_exists")
function_updated_waiter: lambda_waiters.FunctionUpdatedWaiter = client.get_waiter("function_updated")


# Annotated paginators are included as well

import mypy_boto3_lambda.paginator as lambda_paginators

list_aliases_paginator: lambda_paginators.ListAliasesPaginator = client.get_paginator("list_aliases")
list_event_source_mappings_paginator: lambda_paginators.ListEventSourceMappingsPaginator = client.get_paginator("list_event_source_mappings")
list_function_event_invoke_configs_paginator: lambda_paginators.ListFunctionEventInvokeConfigsPaginator = client.get_paginator("list_function_event_invoke_configs")
list_functions_paginator: lambda_paginators.ListFunctionsPaginator = client.get_paginator("list_functions")
list_layer_versions_paginator: lambda_paginators.ListLayerVersionsPaginator = client.get_paginator("list_layer_versions")
list_layers_paginator: lambda_paginators.ListLayersPaginator = client.get_paginator("list_layers")
list_provisioned_concurrency_configs_paginator: lambda_paginators.ListProvisionedConcurrencyConfigsPaginator = client.get_paginator("list_provisioned_concurrency_configs")
list_versions_by_function_paginator: lambda_paginators.ListVersionsByFunctionPaginator = client.get_paginator("list_versions_by_function")

Dynamic type annotations

mypy_boto3 command generates boto3.client/resource type annotations for mypy_boto3_lambda 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("lambda")

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