How to install

VSCode extension

Add AWS Boto3 extension to your VSCode and run AWS boto3: Quick Start command.

Click Modify and select boto3 common and Lambda.

From PyPI with pip

Install boto3-stubs for Lambda service.

# install with boto3 type annotations
python -m pip install 'boto3-stubs[lambda]'


# Lite version does not provide session.client/resource overloads
# it is more RAM-friendly, but requires explicit type annotations
python -m pip install 'boto3-stubs-lite[lambda]'


# standalone installation
python -m pip install mypy-boto3-lambda

From conda-forge

Installing mypy-boto3-lambda from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge
conda config --set channel_priority strict

Once the conda-forge channel has been enabled, mypy-boto3-lambda can be installed with:

conda install mypy-boto3-lambda

It is possible to list all of the versions of mypy-boto3-lambda available on your platform with:

conda search mypy-boto3-lambda --channel conda-forge

How to uninstall

python -m pip uninstall -y mypy-boto3-lambda

Usage

VSCode

• Install Python extension
• Install Pylance extension
• Set Pylance as your Python Language Server
• Install boto3-stubs[lambda] in your environment:

python -m pip install 'boto3-stubs[lambda]'

Both type checking and code completion should now work. No explicit type annotations required, write your boto3 code as usual.

PyCharm

Install boto3-stubs-lite[lambda] in your environment:

python -m pip install 'boto3-stubs-lite[lambda]'

Both type checking and code completion should now work. Explicit type annotations are required.

Use boto3-stubs package instead for implicit type discovery.

Emacs

• Install boto3-stubs with services you use in your environment:

python -m pip install 'boto3-stubs[lambda]'

• Install use-package, lsp, company and flycheck packages
• Install lsp-pyright package

(use-package lsp-pyright
  :ensure t
  :hook (python-mode . (lambda ()
                          (require 'lsp-pyright)
                          (lsp)))  ; or lsp-deferred
  :init (when (executable-find "python3")
          (setq lsp-pyright-python-executable-cmd "python3"))
  )

• Make sure emacs uses the environment where you have installed boto3-stubs

Type checking should now work. No explicit type annotations required, write your boto3 code as usual.

Sublime Text

• Install boto3-stubs[lambda] with services you use in your environment:

python -m pip install 'boto3-stubs[lambda]'

• Install LSP-pyright package

Type checking should now work. No explicit type annotations required, write your boto3 code as usual.

Other IDEs

Not tested, but as long as your IDE supports mypy or pyright, everything should work.

mypy

• Install mypy: python -m pip install mypy
• Install boto3-stubs[lambda] in your environment:

python -m pip install 'boto3-stubs[lambda]'

Type checking should now work. No explicit type annotations required, write your boto3 code as usual.

pyright

• Install pyright: npm i -g pyright
• Install boto3-stubs[lambda] in your environment:

python -m pip install 'boto3-stubs[lambda]'

Optionally, you can install boto3-stubs to typings directory.

Type checking should now work. No explicit type annotations required, write your boto3 code as usual.

Explicit type annotations

Client annotations

LambdaClient provides annotations for boto3.client("lambda").

from boto3.session import Session

from mypy_boto3_lambda import LambdaClient

client: LambdaClient = Session().client("lambda")

# now client usage is checked by mypy and IDE should provide code completion

Paginators annotations

mypy_boto3_lambda.paginator module contains type annotations for all paginators.

from boto3.session import Session

from mypy_boto3_lambda import LambdaClient
from mypy_boto3_lambda.paginator import (
    ListAliasesPaginator,
    ListCodeSigningConfigsPaginator,
    ListEventSourceMappingsPaginator,
    ListFunctionEventInvokeConfigsPaginator,
    ListFunctionUrlConfigsPaginator,
    ListFunctionsByCodeSigningConfigPaginator,
    ListFunctionsPaginator,
    ListLayerVersionsPaginator,
    ListLayersPaginator,
    ListProvisionedConcurrencyConfigsPaginator,
    ListVersionsByFunctionPaginator,
)

client: LambdaClient = Session().client("lambda")

# Explicit type annotations are optional here
# Types should be correctly discovered by mypy and IDEs
list_aliases_paginator: ListAliasesPaginator = client.get_paginator("list_aliases")
list_code_signing_configs_paginator: ListCodeSigningConfigsPaginator = client.get_paginator(
    "list_code_signing_configs"
)
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_function_url_configs_paginator: ListFunctionUrlConfigsPaginator = client.get_paginator(
    "list_function_url_configs"
)
list_functions_by_code_signing_config_paginator: ListFunctionsByCodeSigningConfigPaginator = (
    client.get_paginator("list_functions_by_code_signing_config")
)
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.

from boto3.session import Session

from mypy_boto3_lambda import LambdaClient
from mypy_boto3_lambda.waiter import (
    FunctionActiveV2Waiter,
    FunctionActiveWaiter,
    FunctionExistsWaiter,
    FunctionUpdatedV2Waiter,
    FunctionUpdatedWaiter,
    PublishedVersionActiveWaiter,
)

client: LambdaClient = Session().client("lambda")

# Explicit type annotations are optional here
# Types should be correctly discovered by mypy and IDEs
function_active_v2_waiter: FunctionActiveV2Waiter = client.get_waiter("function_active_v2")
function_active_waiter: FunctionActiveWaiter = client.get_waiter("function_active")
function_exists_waiter: FunctionExistsWaiter = client.get_waiter("function_exists")
function_updated_v2_waiter: FunctionUpdatedV2Waiter = client.get_waiter("function_updated_v2")
function_updated_waiter: FunctionUpdatedWaiter = client.get_waiter("function_updated")
published_version_active_waiter: PublishedVersionActiveWaiter = client.get_waiter(
    "published_version_active"
)

Literals

mypy_boto3_lambda.literals module contains literals extracted from shapes that can be used in user code for type checking.

Full list of Lambda Literals can be found in docs.

from mypy_boto3_lambda.literals import ApplicationLogLevelType


def check_value(value: ApplicationLogLevelType) -> bool: ...

Type definitions

mypy_boto3_lambda.type_defs module contains structures and shapes assembled to typed dictionaries and unions for additional type checking.

Full list of Lambda TypeDefs can be found in docs.

from mypy_boto3_lambda.type_defs import AccountLimitTypeDef


def get_value() -> AccountLimitTypeDef:
    return {...}

How it works

Fully automated mypy-boto3-builder carefully generates type annotations for each service, patiently waiting for boto3 updates. It delivers drop-in type annotations for you and makes sure that:

• All available boto3 services are covered.
• Each public class and method of every boto3 service gets valid type annotations extracted from botocore schemas.
• Type annotations include up-to-date documentation.
• Link to documentation is provided for every method.
• Code is processed by ruff for readability.
