mypy-boto3-elb

Type annotations for boto3 ElasticLoadBalancing 1.40.16 compatible with VSCode, PyCharm, Emacs, Sublime Text, mypy, pyright and other tools.

Generated with mypy-boto3-builder 8.11.0.

More information can be found on boto3-stubs page and in mypy-boto3-elb docs.

See how it helps you find and fix potential bugs:

How to install

Generate locally (recommended)

You can generate type annotations for boto3 package locally with mypy-boto3-builder. Use uv for build isolation.

Run mypy-boto3-builder in your package root directory: uvx --with 'boto3==1.40.16' mypy-boto3-builder
Select boto3-stubs AWS SDK.
Add ElasticLoadBalancing service.
Use provided commands to install generated packages.

VSCode extension

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

Click Modify and select boto3 common and ElasticLoadBalancing.

From PyPI with pip

Install boto3-stubs for ElasticLoadBalancing service.

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

# 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[elb]'

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

How to uninstall

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

Usage

VSCode

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

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

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

PyCharm

⚠️ Due to slow PyCharm performance on Literal overloads (issue PY-40997), it is recommended to use boto3-stubs-lite until the issue is resolved.

⚠️ If you experience slow performance and high CPU usage, try to disable PyCharm type checker and use mypy or pyright instead.

⚠️ To continue using PyCharm type checker, you can try to replace boto3-stubs with boto3-stubs-lite:

pip uninstall boto3-stubs
pip install boto3-stubs-lite

Install boto3-stubs[elb] in your environment:

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

Both type checking and code completion should now work.

Emacs

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

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

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[elb] with services you use in your environment:

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

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[elb] in your environment:

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

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[elb] in your environment:

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

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.

Pylint compatibility

It is totally safe to use TYPE_CHECKING flag in order to avoid mypy-boto3-elb dependency in production. However, there is an issue in pylint that it complains about undefined variables. To fix it, set all types to object in non-TYPE_CHECKING mode.

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from mypy_boto3_ec2 import EC2Client, EC2ServiceResource
    from mypy_boto3_ec2.waiters import BundleTaskCompleteWaiter
    from mypy_boto3_ec2.paginators import DescribeVolumesPaginator
else:
    EC2Client = object
    EC2ServiceResource = object
    BundleTaskCompleteWaiter = object
    DescribeVolumesPaginator = object

...

Explicit type annotations

Client annotations

ElasticLoadBalancingClient provides annotations for boto3.client("elb").

from boto3.session import Session

from mypy_boto3_elb import ElasticLoadBalancingClient

client: ElasticLoadBalancingClient = Session().client("elb")

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

Paginators annotations

mypy_boto3_elb.paginator module contains type annotations for all paginators.

from boto3.session import Session

from mypy_boto3_elb import ElasticLoadBalancingClient
from mypy_boto3_elb.paginator import DescribeAccountLimitsPaginator, DescribeLoadBalancersPaginator

client: ElasticLoadBalancingClient = Session().client("elb")

# Explicit type annotations are optional here
# Types should be correctly discovered by mypy and IDEs
describe_account_limits_paginator: DescribeAccountLimitsPaginator = client.get_paginator(
    "describe_account_limits"
)
describe_load_balancers_paginator: DescribeLoadBalancersPaginator = client.get_paginator(
    "describe_load_balancers"
)

Waiters annotations

mypy_boto3_elb.waiter module contains type annotations for all waiters.

from boto3.session import Session

from mypy_boto3_elb import ElasticLoadBalancingClient
from mypy_boto3_elb.waiter import (
    AnyInstanceInServiceWaiter,
    InstanceDeregisteredWaiter,
    InstanceInServiceWaiter,
)

client: ElasticLoadBalancingClient = Session().client("elb")

# Explicit type annotations are optional here
# Types should be correctly discovered by mypy and IDEs
any_instance_in_service_waiter: AnyInstanceInServiceWaiter = client.get_waiter(
    "any_instance_in_service"
)
instance_deregistered_waiter: InstanceDeregisteredWaiter = client.get_waiter(
    "instance_deregistered"
)
instance_in_service_waiter: InstanceInServiceWaiter = client.get_waiter("instance_in_service")

Literals

mypy_boto3_elb.literals module contains literals extracted from shapes that can be used in user code for type checking.

Full list of ElasticLoadBalancing Literals can be found in docs.

from mypy_boto3_elb.literals import AnyInstanceInServiceWaiterName


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

Type definitions

mypy_boto3_elb.type_defs module contains structures and shapes assembled to typed dictionaries and unions for additional type checking.

Full list of ElasticLoadBalancing TypeDefs can be found in docs.

# TypedDict usage example
from mypy_boto3_elb.type_defs import AccessLogTypeDef


def get_value() -> AccessLogTypeDef:
    return {
        "Enabled": ...,
    }

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:
