# mypy-boto3-lambda [](https://pypi.org/project/mypy-boto3-lambda) [](https://pypi.org/project/mypy-boto3-lambda) [](https://mypy-boto3-builder.readthedocs.io/) Type annotations for [boto3.Lambda 1.14.12](https://boto3.amazonaws.com/v1/documentation/api/1.14.12/reference/services/lambda.html#Lambda) service compatible with [mypy](https://github.com/python/mypy), [VSCode](https://code.visualstudio.com/), [PyCharm](https://www.jetbrains.com/pycharm/) and other tools. Generated by [mypy-boto3-buider 2.2.0](https://github.com/vemel/mypy_boto3_builder). More information can be found on [boto3-stubs](https://pypi.org/project/boto3-stubs/) page. ## How to install Make sure you have [mypy](https://github.com/python/mypy) installed and activated in your IDE. Install `boto3-stubs` for `Lambda` service. ```bash python -m pip install boto3-stubs[lambda] ``` ## How to use ### Client annotations `LambdaClient` provides annotations for `boto3.client("lambda")`. ```python import boto3 from mypy_boto3_lambda import LambdaClient from mypy_boto3_lambda.paginator import ( ListAliasesPaginator, ListEventSourceMappingsPaginator, ListFunctionEventInvokeConfigsPaginator, ListFunctionsPaginator, ListLayersPaginator, ListLayerVersionsPaginator, ListProvisionedConcurrencyConfigsPaginator, ListVersionsByFunctionPaginator, ) from mypy_boto3_lambda.type_defs import AccountLimitTypeDef, ... from mypy_boto3_lambda.waiter import ( FunctionActiveWaiter, FunctionExistsWaiter, FunctionUpdatedWaiter, ) client: LambdaClient = boto3.client("lambda") # 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: LambdaClient = session.client("lambda") ``` ### Paginators annotations `mypy_boto3_lambda.paginator` module contains type annotations for all paginators. ```python client: LambdaClient = boto3.client("lambda") # Explicit type annotations are optional here # Type should be correctly discovered by mypy and IDEs # VSCode requires explicit type annotations list_aliases_paginator: ListAliasesPaginator = client.get_paginator("list_aliases") list_event_source_mappings_paginator: ListEventSourceMappingsPaginator = client.get_paginator("list_event_source_mappings") list_function_event_invoke_configs_paginator: ListFunctionEventInvokeConfigsPaginator = client.get_paginator("list_function_event_invoke_configs") list_functions_paginator: ListFunctionsPaginator = client.get_paginator("list_functions") list_layer_versions_paginator: ListLayerVersionsPaginator = client.get_paginator("list_layer_versions") list_layers_paginator: ListLayersPaginator = client.get_paginator("list_layers") list_provisioned_concurrency_configs_paginator: ListProvisionedConcurrencyConfigsPaginator = client.get_paginator("list_provisioned_concurrency_configs") list_versions_by_function_paginator: ListVersionsByFunctionPaginator = client.get_paginator("list_versions_by_function") ``` ### Waiters annotations `mypy_boto3_lambda.waiter` module contains type annotations for all waiters. ```python client: LambdaClient = boto3.client("lambda") # Explicit type annotations are optional here # Type should be correctly discovered by mypy and IDEs # VSCode requires explicit type annotations function_active_waiter: FunctionActiveWaiter = client.get_waiter("function_active") function_exists_waiter: FunctionExistsWaiter = client.get_waiter("function_exists") function_updated_waiter: FunctionUpdatedWaiter = client.get_waiter("function_updated") ``` ### Typed dictionations `mypy_boto3_lambda.type_defs` module contains structures and shapes assembled to typed dictionaries for additional type checking. ```python def get_structure() -> AccountLimitTypeDef: return { ... } ``` ## Dynamic type annotations `mypy_boto3` command generates `boto3.client/resource` type annotations for `mypy_boto3_lambda` and other installed services. ```bash # 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 ```python # Type is discovered correctly by mypy and PyCharm # VSCode still needs explicit type annotations client = boto3.client("lambda") session_client = boto3.Session().client("lambda") ```
