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==1.39.0' mypy-boto3-builder
Select boto3-stubs AWS SDK.
Add EVS 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 EVS.

From PyPI with pip

Install boto3-stubs for EVS service.

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

# 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[evs]'

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

How to uninstall

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

Usage

VSCode

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

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

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[evs] in your environment:

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

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[evs]'

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[evs] with services you use in your environment:

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

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[evs] in your environment:

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

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[evs] in your environment:

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

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-evs 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

EVSClient provides annotations for boto3.client("evs").

from boto3.session import Session

from mypy_boto3_evs import EVSClient

client: EVSClient = Session().client("evs")

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

Paginators annotations

mypy_boto3_evs.paginator module contains type annotations for all paginators.

from boto3.session import Session

from mypy_boto3_evs import EVSClient
from mypy_boto3_evs.paginator import (
    ListEnvironmentHostsPaginator,
    ListEnvironmentVlansPaginator,
    ListEnvironmentsPaginator,
)

client: EVSClient = Session().client("evs")

# Explicit type annotations are optional here
# Types should be correctly discovered by mypy and IDEs
list_environment_hosts_paginator: ListEnvironmentHostsPaginator = client.get_paginator(
    "list_environment_hosts"
)
list_environment_vlans_paginator: ListEnvironmentVlansPaginator = client.get_paginator(
    "list_environment_vlans"
)
list_environments_paginator: ListEnvironmentsPaginator = client.get_paginator("list_environments")

Literals

mypy_boto3_evs.literals module contains literals extracted from shapes that
can be used in user code for type checking.

Full list of EVS Literals can be found in
docs.

from mypy_boto3_evs.literals import CheckResultType


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

Type definitions

mypy_boto3_evs.type_defs module contains structures and shapes assembled to
typed dictionaries and unions for additional type checking.

Full list of EVS TypeDefs can be found in
docs.

# TypedDict usage example
from mypy_boto3_evs.type_defs import CheckTypeDef


def get_value() -> CheckTypeDef:
    return {
        "type": ...,
    }

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.
